Find Your Undertone

Warm, cool, or neutral — learn how to identify your skin undertone using vein color, jewelry test, sun reaction, and wrist-light tests.

  1. The Vein Test: Look at the veins on the inside of your wrist in natural light. Green or greenish veins indicate warm undertone. Blue or purple veins indicate cool undertone. A mix of both means neutral undertone.
  2. The Jewelry Test: Hold silver jewelry against your bare skin, then gold. If gold looks more natural and flattering, you have warm undertone. If silver looks better, cool undertone. Both equal means neutral.
  3. The White Fabric Test: Hold bright white fabric next to your face, then warm ivory or cream. If bright white makes you look fresher, you're cool. If warm ivory is more flattering, you're warm.
  4. The Sun Reaction Test: If you tan easily and develop a golden tan, you're warm. If you burn easily or turn pink before tanning, you're cool. Moderate tanning with occasional burning suggests neutral.
  5. The Eye and Hair Pattern Test: Warm undertone people tend to have brown, hazel, or warm green eyes with golden or warm brown hair. Cool undertone people tend to have blue, gray, or cool green eyes with ash blonde or cool brown hair.
  6. The Flash Photo Test: Take a photo with flash in a white-walled room. If your skin looks yellow or golden, you're warm. If it looks pink or gray, you're cool. Hard to tell means neutral.

Frequently Asked Questions

What is the most accurate way to find your skin undertone?

The most reliable method is to use multiple tests together and look for consensus. The vein test, jewelry test, and white vs. ivory fabric test are the three most reliable individual tests. If at least two of the three point in the same direction, that's your undertone. If they conflict, you're likely neutral.

Can your undertone change over time?

No — your undertone is determined by the pigments in your skin at the subsurface level and does not change with age, tanning, or seasons. What changes is your surface skin tone. This is why your color season stays consistent throughout your life.

What's the difference between warm and neutral undertone?

Warm undertone has a clear golden or peachy quality — gold jewelry is noticeably more flattering than silver. Neutral undertone is balanced — both gold and silver look equally good. Neutral-undertoned people tend to fall in the "Soft" seasons.

Can you have warm undertone but cool skin tone?

Yes — someone with fair, pale skin can absolutely have a warm undertone, and someone with deep skin can have a cool undertone. Surface color and undertone are independent of each other.

What undertone do I have?

Use multiple tests together: the vein test (green = warm, blue/purple = cool), the jewelry test (gold flatters warm, silver flatters cool), and the white vs. ivory test. If two of three agree, that's your undertone.
