How to Find Your Undertone With Makeup On

To find your undertone with makeup on, test the bare skin that foundation does not cover: your neck, chest, ears and inner arm in soft daylight, with gold against silver and white against cream, then wipe one clean patch on your cheek to confirm. Makeup changes surface color, so never judge undertone from a made-up cheek.

The short version: makeup is the one thing that can fool every undertone test, because it is designed to change how your skin looks. The fix is to find bare skin, use tests that rely on large areas of color, and treat your own foundation only as a clue. This guide is part of our wider walkthrough in the skin tone analyzer guide.

The quick answer

You do not have to wipe your face to learn something useful, but you do need to know which makeup gets in the way and which does not. Follow these steps in order.

1. Check the clean spots first. Your neck, chest, ears, inner arm and the skin along your hairline are usually bare, and they share your undertone.
2. Use daylight. Stand beside a window in indirect light. Warm bulbs and cool LEDs both distort color.
3. Test your bare skin where you can. Even a cotton pad and some micellar water on one cheek gives a clean patch to compare.
4. Run three tests. Jewelry, white versus cream, and sun reaction. Look for agreement.
5. Treat your foundation as evidence. The shade that disappears into your neck is a clue, but it is not proof.

If you want a second opinion that does not depend on your own eye, the Tone & Fit app reads skin, hair and eyes from a selfie. Photos taken without makeup give the cleanest result.

Why makeup confuses undertone tests

Every undertone test compares your skin with a reference: metal, paper, fabric. Makeup is a layer of pigment designed to change how your skin looks, so it changes the thing you are trying to read. Foundation shifts color and evenness, blush and bronzer add pink or orange, concealer lightens, and tinted moisturizers and BB creams add their own cast. Even a product that claims to match your skin usually has its own undertone, which may or may not be the same as yours.

The other problem is that makeup is usually chosen to match what you believe your undertone is. If you have been wearing a foundation that is slightly too yellow or slightly too pink for years, it can feel normal, and it can make your skin look like the wrong undertone when you test against it. That is why the first rule is to find places where there is no product at all.

This guide belongs to our wider walkthrough in the skin tone analyzer guide, and it builds on the basics in how to find your skin undertone at home. It is a color guide and not medical advice. If concealer is what is in the way, our guide to finding your undertone when you have dark circles shows which skin to test instead.

Makeup color versus undertone

Undertone is the steady cool, warm, neutral or olive base beneath the surface of your skin. Makeup only changes the surface. We explain the distinction in undertone versus overtone, and the same logic applies to other surface effects, such as a tan in how to find your undertone with a tan or redness in how to find your undertone with redness. The goal with makeup on is simply to look past the layer, or work around it.

Where to find bare skin when your face is covered

You will almost always have areas that have no makeup on them. These are your best test sites.

• The neck and upper chest. Foundation usually stops at the jaw, and the chest below the collarbone is typically untouched. Sun exposure may make it slightly deeper, but the undertone matches your face.
• Behind the ear. This skin is protected from the sun and rarely has product on it.
• The inner forearm and inner wrist. These areas see less sun and have no makeup.
• The hairline and the area beside the ear. If your foundation does not blend all the way, the edge shows your natural color.

Compare these areas with the skin on your cheek. If the foundation matches your neck, it is probably close to your own undertone. If it looks yellower, pinker or greyer than your neck, the product has its own color cast.

Make a clean test patch

If you want a more direct read, create a small bare patch.

1. Soak a cotton pad in micellar water or cleansing oil.
2. Wipe a stripe about the width of two fingers on one cheek, from the cheekbone toward the jaw.
3. Pat it dry and wait two minutes so any redness from rubbing can settle.
4. Look at the stripe beside the area still covered, in daylight.

You now have a before-and-after right on your face. Hold gold and silver jewelry against the bare stripe, and notice which one looks cleaner. If the bare patch looks more yellow-green than your foundation, you may lean warm or olive. If it looks pinker or bluer, you may lean cool. Wipe the patch gently, and do not scrub, because irritated skin turns pink and will mislead you.

If you would rather not remove makeup at all, skip ahead to the tests that do not depend on your face.

Set up the conditions

• Light: soft daylight beside a window, with no direct sun on your face. See why your color season seems to change in different lighting for how much light changes everything.
• Mirror: use a mirror that does not tint, and avoid lighted makeup mirrors, which are designed to flatter and often shift color.
• Surroundings: wear a plain white or grey top and keep colorful walls out of view.
• Timing: late morning works well. Skin is pink right after exercise, a hot shower or a glass of wine.

The jewelry test with makeup on

Hold a piece of yellow gold and a piece of silver against your bare neck, jawline and chest, not your made-up cheek. If gold makes the skin glow and silver looks gray or flat, you lean warm. If silver looks crisp and gold looks sallow, you lean cool. If both look fine, you may be neutral or olive. Our guide to gold or silver jewelry for your undertone covers how to read the result, and the best watch metal for your skin tone shows how the same test applies to a watch on your wrist.

The white versus cream test

Hold a sheet of stark white paper under your chin, next to your neck and chest, and then a sheet of cream or ivory. Stark white that makes you look fresh and cream that makes you look yellow suggests cool. Cream that looks warm and healthy while white looks harsh suggests warm. Because this test works with large areas of color, it is easier to do on unmade neck and chest skin than on your face.

You can extend it by draping fabric. Our guide to color draping at home shows how to compare cool and warm colors under your chin and decide which makes the skin look smoother. If you are draping, remove or wipe away heavy blush and bronzer first, because they pick up the color of the fabric and confuse the comparison.

The sun reaction question

This test uses history, not appearance, so makeup cannot affect it. Think about how your skin behaves in the sun without protection. Skin that burns or pinks first and tans slowly often leans cool. Skin that goes golden or bronze easily often leans warm. Skin that does a bit of both is often neutral or olive. It is a hint and not a diagnosis, and sun safety matters more than any color test.

Veins, with caution

The vein check is the weakest of the common tests. Blue or purple veins tend to go with cool, green with warm, and a mix with neutral, but the color of the skin above the vein changes how they look, and it is hard to judge under makeup or tan. Treat it as a tie-breaker at most. Our piece on what blue or green veins mean explains the limits.

Use your foundation as a clue

If you wear foundation regularly, it can give you hints, as long as you treat them carefully. Here is how to read it.

• Does it blend into your neck? If the shade disappears at the jaw, it is close to your skin in both depth and undertone.
• What does the shade name suggest? Many brands label shades as cool, warm, neutral or olive. If the shade you wear is labeled warm, that is a clue, but brand labels are not standardized, so use it only as a hint.
• Does it look orange or ashy? An orange cast usually means the shade is too warm or too deep for you. An ashy or greyish cast usually means it is too cool or too light.
• Does it oxidize? Some foundations darken after a few hours. If yours looks fine when applied and orange later, the formula is the problem and not your undertone.

Our guides on how to find your foundation undertone, foundation shade by undertone and the best foundation undertone match show how to go the other way: once you know your undertone, how to choose a base that fits.

What blush, bronzer and lipstick can tell you

Cheek and lip color reveal a surprising amount, because the colors that look natural on you tend to match your undertone. If berry and rosy pinks look natural and peach looks off, you probably lean cool. If peach, coral and terracotta look natural and blue-pinks look harsh, you probably lean warm. If a soft rose or dusty coral works, you may be neutral. This is not a replacement for the earlier tests, but it is a good cross-check. See blush by undertone and the best lipstick color for your undertone for shade ideas.

Photos with makeup on

A photo of yourself in full makeup will show the makeup, not your skin. Phone cameras also adjust white balance and smooth skin automatically, which shifts the color further. Our article on why your phone camera lies about skin tone explains the problem, and the at-home phone camera tutorial shows how to take a better picture.

For a photo-based result, take the selfie bare-faced if you can. Use soft daylight, turn off beauty filters and portrait smoothing, and keep your hair away from your face. If you must wear some makeup, keep it minimal and avoid heavy contour, bronzer and highlighter. The Tone & Fit app analyzes skin, hair and eyes together, and its result will be most reliable on a clean, well-lit photo. Our color analysis app guide explains what these tools measure and where they have limits.

How to read mixed results

Mixed results are common and usually informative.

• Mostly cool answers: you probably lean cool. The cool skin tones explainer covers what that means.
• Mostly warm answers: you probably lean warm. See the warm skin tones explainer.
• An even split: you are likely neutral, covered in neutral undertone skin.
• A greenish gold cast with no clear pattern: you may be olive. Read olive undertone explained and how to tell if olive skin is warm or cool.

If you are still stuck, do not force a decision. Wear colors from the neutral range for a few weeks and notice how they look in daylight. Our guide to determining skin undertone compares the tests by reliability, and the personal color analysis guide explains how undertone connects to the rest of the system.

After you know your undertone

Once you have an answer, it connects to a season and a palette. If the system is new to you, start with the seasonal color analysis explainer and the overview of the 12 color seasons, then use the find my color season guide to narrow it down. For clothing, the guide to what colors look good on you turns your result into a wardrobe.

It is also worth re-checking your makeup. If your foundation, blush and lipstick all share an undertone that is not yours, you may find your face looks better, and your routine gets simpler, when you switch to shades that match. Our guide to eyeshadow by color season extends the same idea to your eyes.

Common mistakes

• Testing on a made-up cheek. The product is the thing you are reading. Use the neck, chest, ear and arm.
• Trusting a foundation label. Brands do not agree on what warm, cool or neutral means.
• Using a lighted makeup mirror. These tint skin and make comparisons unreliable.
• Rubbing your skin raw. Irritation turns skin pink and fakes a cool result.
• Relying on one test. Each test has a weakness. Look for agreement across at least three.
• Testing in warm indoor light. Bulbs change the color of everything, so use daylight.
