Cool Winter makeup: cold, clear shades and how to wear them
Cool Winter makeup - True Winter, in some systems - is makeup with the gold taken out: icy lavender and silver on the eyes, cool pink and berry on the cheeks, crimson, cerise and cherry on the mouth, and black at the lashes. What it cannot carry is warmth, and after that, dust. Further down: sixteen complete faces on four skin depths, each step in its place, and a single list of all 44 shades.
- Four steps, in order
- Four complexions
- Everyday and evening
The order you apply it in
Start here
You are a Cool Winter. This is your makeup.
One fact drives everything below: your coloring is cold. Skin from porcelain to deep brown with a blue-pink undertone and no gold in it, hair from ash brown to blue-black - or silver, once it turns - and clear eyes against bright whites. The contrast is medium to high, and crisp rather than soft.
So the shades are the cold end of your palette worn on the face, and there are two ways to miss. Warm makeup - bronze, peach, camel - turns the skin yellow. Dusty makeup - mauve, dusty rose, taupe-brown - belongs to Cool Summer, and on this face it looks tired.
Keep every shade cold and clear, and let one feature at a time be the strong one.

Sixteen finished looks
Start with the faces: four women, four occasions each, and every shade written beside the photo it is in. Pick the row whose skin is nearest yours and follow it left to right. It ends on the strongest face this coloring carries - a charcoal or jewel-toned eye with a crimson, cherry or plum mouth.

Follow one occasion down its column and the names change from row to row. A cool pink that is obvious on porcelain skin barely registers on deep brown, so every row down uses a deeper shade - cool pink, raspberry, plum, berry - to get the same result. The temperature is the one thing that holds still. Why these shades rather than the ones in your bag is the next section.
Why these shades, and not the ones you own
Look closely at the sixteen faces and four swaps carry most of them. Each is below, beside what a Cool Winter usually has in the drawer already: brown liner, a camel palette, coral blush, and the dusty rose lipstick she bought when someone told her she was "cool".
Why these shades and not those
Tap a productBrown liner is sold as the softer choice, and it is also the warmer one: red and gold in the pigment. Around a cold eye under dark brows it reads as a faded, slightly rusty line. Black, or midnight navy, keeps the eye as clear as it already is.
Camel and caramel fill the best-selling neutral palettes. On blue-pink skin they sit on the lid as a yellowish smudge. A gray taupe gives the lid the same depth with none of the gold.
This skin flushes pink, never peach. Coral lands on it as a separate orange patch and makes the rest of the face look sallow by comparison. A cool pink of the same strength reads as your own flush.
The over-correction. Told to "go cool", many Cool Winters land on a dusty rose: the right temperature, but grayed and soft. That is Cool Summer’s lipstick. On this contrast it looks tired rather than natural, where a cerise or crimson of the same coolness looks awake.
The right shade moves with the skin - cool pink on a porcelain cheek, berry on deep brown - which is why no one hex fits everybody; the cheat-sheet lists yours. The wrong shade never moves: warmth and dust fail at every depth, because every Cool Winter has cold skin. Liner is the constant, black on all four. The swatches on the "What goes wrong" side illustrate the mistake; they are not measured products.
Three of the four miss on temperature. Cool Winter is the coldest coloring there is, a blue-pink undertone at every depth with no gold anywhere, so a brown, camel or coral puts in the one thing the face does not have. The fourth misses on clarity: your palette is clean color, cerise and sapphire rather than rose and slate, and a shade with gray in it lowers the contrast between your skin and your hair.
That settles what to buy. Where each one goes, and how much of it, is easier to see than to read.
How to build it, step by step
Here are the same swaps in the order they go on. Choosing the shade is half the job. The other half is how it goes on, and on a face this clear that decides whether cold color looks like your own coloring or like makeup.
-
Base
Cold, even skin, and no more of it than you need
Your base shades, by depth
The season sets the undertone - cool or neutral, with a pink or slightly gray base. Your own skin sets the depth.
Fair - Foundation Fair - cool porcelain #F2E2E0
- Bronzer Fair - cool taupe #8E8177
- Highlighter Fair - silver glow #E6E8EC
Light - Foundation Light - rose beige #EBD3CE
- Bronzer Light - smoky taupe #7A6D66
- Highlighter Light - icy pearl #EFEAF0
Medium - Foundation Medium - cool walnut #C0977E
- Bronzer Medium - gray-brown #665A57
- Highlighter Medium - platinum glow #DDE0E4
Deep - Foundation Deep - cool mocha #6E4B42
- Bronzer Deep - charcoal brown #544948
- Highlighter Deep - pink pearl #F0D9DF
Cool Winter skin tends to look clear on its own, so the base is there to even it out, not to cover it. Press a cool foundation into the center of the face where the redness sits, and let it fade to nothing toward the hairline and jaw. If the jawline shows a stripe in daylight, the shade is too warm - a lighter or darker golden one will not fix it.
Contour replaces bronzer. A cool taupe one step darker than your skin goes into the hollow under the cheekbone and blends upward until it reads as shadow. Then one sweep of silver, pearl or platinum along the top of the cheekbone, and nowhere else: light on the high points, cold light only.
Tip Check the base at a window before you leave the house. Indoor light is warm and forgives a golden foundation that daylight will not.
-
Cheeks
A pink flush, placed high
Blush goes on before the eyes, so the eye makeup can be balanced against it. This skin flushes pink or berry, and a cream in that color reads as your own. Tap it onto the top of the cheekbone rather than the apple, then blend up and back toward the temple: placed high, a clear color lifts the face; placed low, it looks like a flush from the cold.
Blush
Cool pink on the fairest cheek, berry on the deepest, each step a little deeper and cooler. Choose the one nearest the color your cheeks go after a brisk walk.
Cool pink blush #E1A3B1
Raspberry blush #D2436E
Plum blush #9E4F72
Berry blush #B03060 Tip If the blush looks like a patch, it is the placement, not the shade: blend the top edge up into the temple until you cannot find where it stops.
-
Eyes
Groomed brows, one cold shade, a line at the lashes
Brows first, because they already carry most of this face’s contrast: brush them up and fill only the gaps, in a cool shade matched to your hair. Then one shade across the lid - icy lavender or silver gray on fair skin, smoky gray or gray taupe as the skin deepens. Then a thin line pressed into the upper lash roots, navy or graphite if black feels like too much by day, and black mascara from root to tip.
Brows
Four cool shades, chosen by your hair rather than your skin. Black-brown or cool dark brown for dark hair, soft graphite or ash taupe once it turns silver.
Ash taupe #7C736B
Soft graphite #54545C
Cool dark brown #4A3A38
Black-brown #2A2422 Everyday eyeshadow
One shade over the moving lid, softened up to the crease line and stopped there. Icy lavender brightens blue and gray eyes; gray taupe gives brown ones depth without warming them.
Icy lavender #CBC3DE
Silver gray #B9BDC4
Smoky gray #8A9099
Gray taupe #8C8177 Eyeliner
Four colors, not four depths - every complexion can wear all of them. Black is safe on everyone; midnight and graphite are the daytime versions that still read as dark, plum ink the one to try at night.
Graphite #4A4A50
Plum ink #54254A
Midnight #1B2A4A
Jet black #141414 Mascara
Black or blue-black on everyone. Brown mascara fades against dark brows, and the blue in a blue-black makes the whites of the eyes look whiter.
Graphite #4A4A50
Midnight #1B2A4A
Blue-black #14161C
Jet black #141414 Tip On silver hair, keep the brows a shade softer than they were - soft graphite rather than black-brown - and keep the black at the lashes. The contrast moves from the brows to the eyes.
-
Lips
A nude with pink in it
The Cool Winter nude is a cool rose beige, a cool pink, a soft plum or a raspberry - shades that look like color in the tube and like your own lips on the mouth. Apply straight from the bullet and keep the edge clean: a crisp line suits a clear coloring better than a blurred, finger-pressed stain.
Nude lips
Rose beige for the fairest mouth, raspberry for the deepest. When it is right, it looks like your own lips in better light.
Rose beige nude #C99BA0
Cool pink nude #D98BA0
Plum nude #9E6C7E
Raspberry nude #B85C7A Tip If a nude makes your teeth look yellow, there is peach in it. Go one step pinker, not lighter.
That is the day face: cold, clean and quiet. At night the same face can take a lot more, and the next section shows how much.
Your evening face: what changes, and what must not
Night is where Cool Winter makeup gets to be as strong as the coloring, and even then only two things move. The outer eye goes dark, and the mouth moves from a cool nude to a clear pink or a blue-red. The rest is the morning face, untouched. Every depth appears twice, one woman by day and the same woman at night.
Eyes
At night the lid keeps its day shade and the outer third goes dark: emerald, blackberry, charcoal or night blue, from the crease round under the lower lashes. The icy or gray base underneath is what stops a deep color from turning muddy.
- Keep the day shade across the lid.
- Press the dark shade into the crease and over the outer third.
- Take a touch under the outer half of the lower lashes and stop there.
- Keep the center of the lid in the day shade; that is what keeps the eye open.
- Line the upper lash roots in black, navy or plum, and blur the places where the shades meet.
The rule Stronger and darker, never warmer. A bronze or brown smoky eye is the one evening eye that fights this face; charcoal, navy or plum of the same depth is the one that belongs to it.
Icy lavender stays on the lid, emerald fills the crease and the outer corner, and black sits in the lash line. Green next to pale blue eyes makes the blue look icier, and with porcelain skin and black hair it looks intended, not loud.
Deepest at the outer corner
Center of the lid stays lightest
Lower lashes: outer half only
Silver gray on the lid, blackberry worked into the crease and out past the corner, plum liner at the lashes. A plum smoke deepens brown eyes, and next to silver hair it puts back the contrast the hair has lost.
Deepest at the outer corner
Center of the lid stays lightest
Lower lashes: outer half only
Smoky gray on the lid, charcoal round the outer corner, a black line underneath. The classic gray smoke is at its best on olive skin with black hair: all the depth, none of the brown.
Deepest at the outer corner
Center of the lid stays lightest
Lower lashes: outer half only
Gray taupe on the lid, night blue carried out to the corner, a midnight line at the lashes. On deep cool skin a navy shimmer catches the light the way a matte black never does, so the eye stays bright.
Deepest at the outer corner
Center of the lid stays lightest
Lower lashes: outer half only
Lips
The day nude and the evening lip belong to one cold family - rose beige to cerise, cool pink to crimson, plum to cherry - so choosing the evening shade mostly means choosing how strong. A blue-red at night is this coloring’s signature, not its risk.
- Press the first layer in with a brush.
- Blot once.
- Add a second layer through the center of the mouth, then sharpen the outline.
- A crisp line suits this coloring - keep it on your own lip line.
The rule The shade comes from your depth. The time of day only sets how much of it you wear.
Rose beige by day, cerise after dark. A clear blue-pink on porcelain skin is as bright as this coloring goes, and it needs little else around it.
Keep the edge crisp
Build through the middle
Cool pink by day, crimson after dark. A true blue-red is the most flattering thing a silver-haired Cool Winter can wear on her mouth, and it whitens the teeth as it goes.
Keep the edge crisp
Build through the middle
Plum nude by day, cherry after dark. A deep cherry holds its own next to a charcoal eye without competing with it.
Keep the edge crisp
Build through the middle
Raspberry by day, cherry after dark. For the biggest evening, deep plum at the end of the ladder is darker still and sits beautifully on deep cool skin.
Keep the edge crisp
Build through the middle
What must not change
It keeps the icy or gray day shade. Dark color from lash to crease shrinks the eye rather than framing it.
Same cool pink or berry, same amount. A blue-red lip and a strong cheek together look painted.
They are already the darkest thing on the face; drawing them darker for the evening makes them the first thing anyone sees.
No extra powder. Under a flash a heavily powdered cool base goes gray, and a little glow is what keeps a red mouth looking fresh.
In short: at night go stronger and darker, never warmer. Whether a product manages that comes down to its color, and to one property most labels barely mention.
Why the right shade can still look wrong
If it is not the shade, it is usually the finish. A product has a color and a surface, and the surface - the amount of light it throws back, and whether that light is clear, white or gold - almost never makes it onto the label. Below: one lipstick on one mouth in four finishes, the red identical in every frame.
One shade, four finishes
Across the four frames the shine is what changes. Matte gives back no highlight at all; satin spreads a soft one along the lip; gloss collects it into a single bright point; frost scatters it over the whole mouth as shimmer. That bright reflection off a smooth surface is the specular highlight, and it is most of what we read as finish.
Then there is what the shine is made of, and for a Cool Winter that settles the verdict. Clear gloss is light and nothing else, so a cold color stays cold under it. Silver and white pearl are cold too, which makes them yours on a lid or a cheekbone and a problem only over a deep lip, where they pale it. Gold shimmer is the one to leave: it warms whatever it touches. In a shop, tilt the product under a lamp - a silver or clear flash is yours, a gold one is not.
The same question, on skin
Finish matters even more on a cheek, since skin brings a texture of its own that a product either keeps or covers. The left photograph of each pair keeps it.
What that means, product by product
- Base
- Satin or natural, cool or neutral. Matte only where you shine.
- Blush
- Cream or powder in cool pink, raspberry, plum or berry, the edge blended away.
- Eyeshadow
- Matte and satin by day; emerald, night blue, plum and silver shimmer at night. Skip gold, bronze and copper.
- Brows
- Tinted gel or a soft powder in a cool shade that matches your hair. Leave the waxy pencils.
- Lips
- Matte, satin or clear gloss - all three work. Frost stays off the mouth.
- Highlighter
- Silver, platinum or pink pearl, blended to no edge. Gold reads yellow.
Take the shine off the center of the face and leave the rest: a translucent or cool-toned powder over forehead, nose and chin, nothing on the cheekbones, and blotting paper during the day. A face matte from edge to edge loses the clarity that lets the strong colors on this page look effortless rather than stern.
How to get the right one home
None of it helps unless the shade you carry home is the right one, and shade lists rarely cover how. This part does: a test that actually works, the label words that betray a warm or dusty product, and why a swatch on the back of your hand settles nothing.
The jaw test
- Paint three candidates from the jawline down onto the neck, not on the wrist or the hand.
- Blend all three out.
- Walk them to a window. Warm shop light can make a golden base pass for neutral even on the coldest skin.
- Buy the stripe that has vanished - not the one that looks nicest, the one you can no longer find.
Where you sit on the foundation grid
Every foundation range is laid out on the same grid, depth down one side and undertone across the top, whether or not the stand shows it. Here is that grid with the Cool Winter squares outlined - all of them in the coolest column.
At every depth the request is the same: a cool letter at your number. A porcelain Cool Winter and a mocha one differ in the number only, so ask for your depth plus cool, not for a shade name from an ad.
A word on what the chart can and cannot do. The cool squares hold this site’s values, not any brand’s; every range mixes its letters a little differently and depth numbers do not transfer between brands, so nothing here can be ordered sight unseen. The neutral, olive and golden squares are there to illustrate - your cool shade nudged warmer and labeled the way a shop would label it. Neutral is the only maybe, and on the coldest coloring there is it fails more often than it passes: the jaw decides.
Reading a shade name
Two traps, and the second one catches the readers who already avoid the first. The first is the soft default: natural, nude, beige, sand, which in most ranges lean golden because golden is what the industry treats as neutral. The second is the dusty default: mauve, rosewood, soft rose. Those are cool enough, and they are Cool Summer’s. The words that carry what you need are the cold ones and the clear ones: icy, silver, cherry, blue-red.
What the finish words on a label actually mean
- Satin, natural, second-skin
- The everyday answer for the base.
- Gloss, vinyl, lacquer
- Clear shine suits a clear coloring - on a crimson or a cherry it looks crisp, not wet.
- Radiant, luminous, glow
- Tilt it under a lamp: a silver, platinum or pink-pearl flash suits you, a gold one does not.
- Metallic, foil, chrome
- Silver, night-blue or emerald foil on the lid works at night; gold, bronze or copper foil does not.
- Frost, pearl-finish, iridescent
- The pearl is cold, so it can suit a lid or a cheekbone. On a red lip it pales the color - keep it off the mouth.
Judging a swatch photo online
Product photos are lit bright, flat and slightly warm, which is the one light that hides what a Cool Winter needs to see. A cold shade comes out softer than it is, a warm one passes for neutral, and a raspberry and a coral can look like sisters. Trust swatches on skin over the pan, and photos with a shadow in them over flat, bright ones - where the light drops off, the undertone comes through.
Ranges are reformulated, renamed and retired every season, so any product list on this page would be out of date within months and cost readers money each time it was. A hex, a few label words and the jaw test keep: they work in every shop and on brands this page will never have heard of.
When it does not work
The shades, their order and a way to test them in the shop are all behind you now. This part is for the morning the mirror says something is off and no single product is the obvious culprit.
Two ways it goes wrong
The makeup looks harsh
- What it looks like
- In a photo you see eyes and a mouth and not much face between them. The skin looks paler and older than it is, and someone asks where you are going tonight.
- Why
- Too many strong points at once: black all the way round the eye, a dark lip and a sculpted cheek on the same face. Cool Winter carries strong color, but its contrast is medium to high, not Deep Winter’s, and at the lighter depths, or with hair going silver, three statements outweigh the features they sit on.
- Fix
- Keep one strong point and quiet the rest. A crimson lip with just liner and mascara, or a charcoal eye with a cool pink nude. The color stays as clear as before; there is simply less of it.
You look tired and flat
- What it looks like
- Everything is on and the face still looks gray. The mouth fades, the shadows under the eyes show, and your hair and eyes are the only clear things in the picture.
- Why
- The makeup is soft: dusty rose, mauve, taupe-brown, a beige nude. These are built for Cool Summer’s lower contrast. Next to clear eyes and dark hair, gray in the makeup reads as fatigue in the face.
- Fix
- Go clearer, not warmer. Cerise or cool pink instead of dusty rose, raspberry instead of mauve, silver gray instead of taupe-brown, and a black line at the lashes. It looks bright in the pan and like your own face in the mirror.
And the shades that never work
Each swatch below fails for one of three reasons, and its tag says which; warmth is by far the most common. Once the three make sense, you can judge a shade that is not on the list: it is making one of these mistakes, or none.
Base and glow
- Golden beige foundation warm
- Orange bronzer warm
- Gold highlighter warm
- Dark contour stripe heavy
Cheeks
- Peach blush warm
- Terracotta blush warm
- Dusty mauve blush dull
- Burgundy-brown blush heavy
Eyes
- Copper shimmer warm
- Khaki green dull
- Dusty sage dull
- Matte black all over the lid heavy
Lips
- Orange-red warm
- Beige-peach nude warm
- Dusty rose dull
- Brown-black lip heavy
Why each one fails
- warmToo warm
- Golden, peach, coral, orange, copper, camel. Most ranges treat these as neutral, which is why they end up in a Cool Winter’s bag. On blue-pink skin they read yellow, and the teeth go yellow with them.
- dullToo dusty
- Mauve, sage, khaki, dusty rose. Sometimes the right temperature, but grayed - Cool Summer’s shades. Against clear eyes and dark hair they look tired rather than soft.
- heavyToo dark and dense
- Brown-black lips, a black lid from lash to brow, a dark contour stripe. Cool Winter has contrast, not Deep Winter’s weight: darkness with brown in it, or spread over a large area, looks heavy rather than striking.
Read the tags rather than the swatches: each swatch just illustrates its mistake, and its hex is an example, not a measured product. If the dusty swatches flatter you more than this page suggests, read Cool Summer, the soft neighbor with the same coolness. If the darkest, densest shades suit you, look at Deep Winter.

Three rows ignore skin depth. Eyeliner and mascara are colors, not depths: any complexion can wear graphite, midnight, plum ink or blue-black, and jet black is the everyday pick for both. Brows go by your hair: black-brown or cool dark brown for dark hair, soft graphite or ash taupe once it turns silver. The contour row is cool taupe, never bronze. The palette page shows the base on four complexions, plus the clothing colors all of this comes from. The full Cool Winter palette →

Where this came from
Six sources, and the claim each one supports: that makeup works through facial contrast and that the right amount depends on the face; what a natural flush is; why depth and undertone are two separate choices in a foundation; how we see gloss; and why store lighting hides a golden base.
-
Aspects of facial contrast decrease with age and are cues for age perception (opens in a new tab)
Porcheron, Mauger & Russell, PLoS ONE, 2013
Behind the whole page. Facial contrast - how far the eyes, brows and mouth stand out from the skin - can be measured, makeup raises it, and people read it as a cue to age. A Cool Winter face starts with medium to high contrast: dark or silver hair and clear eyes against cool skin. Makeup that keeps that contrast looks like the face; makeup that lowers it, a dusty rose or a beige nude, looks like tiredness.
-
Differential effects of makeup on perceived age (opens in a new tab)
Russell, Batres, Courrèges et al., British Journal of Psychology, 2019
Behind the two ways it goes wrong. In controlled photographs, makeup made women in their forties and fifties look younger and women of twenty look older. How much a face can carry depends on the face, which is why the fix for a harsh look is fewer strong points, not softer colors.
-
Skin blood perfusion and oxygenation colour affect perceived human health (opens in a new tab)
Stephen, Coetzee, Law Smith & Perrett, PLoS ONE, 2009
Behind the cheeks step. Asked to make a face look as healthy as possible, people add the color of oxygenated blood under the skin. On blue-pink skin that flush is cool pink or berry, which is why raspberry reads as color from inside and coral reads as an orange patch on top.
-
Non-invasive measurements of skin pigmentation in situ (opens in a new tab)
Stamatas, Zmudzka, Kollias & Beer, Pigment Cell Research, 2004
Behind the two axes of the shade grid. Skin color carries two signals: melanin sets the depth - your row - and hemoglobin adds its own, and the two have to be separated to measure either. That is why the cool undertone is a column you choose, and why a lighter or darker golden shade never fixes a yellow cast.
-
The dark side of gloss (opens in a new tab)
Kim, Marlow & Anderson, Nature Neuroscience, 2012
Behind finishes. We read gloss from specular highlights and their dark counterparts, and the effect disappears when they are blurred. A clear coloring suits a crisp highlight: a clean satin or a gloss keeps a blue-red looking like a blue-red, where a heavy blurring powder grays it.
-
CIE 13.3-1995: Method of measuring and specifying colour rendering properties of light sources (opens in a new tab)
International Commission on Illumination (CIE), 1995
Behind the jaw test in how to shop. Light sources are rated on how faithfully they render the colors under them, and shop lighting rates low. Warm store light makes a golden foundation look neutral on the coolest skin there is, so the test belongs at a window.
Where the line falls. The contrast research, the skin biology, the gloss perception and the lighting standard above are sourced. Which shades belong to a Cool Winter, which suits which depth, and where strong turns into harsh on this coloring are our own analysis, built from the palette on the parent page. No study covers that, and we would rather say so than borrow a citation that does not.
