🌗 Undertone
Warm vs Cool Undertone
4 home tests that actually work, plus what to do if you're neutral.
Your undertone is the color underneath your skin's surface — warm (yellow/peach/golden), cool (pink/red/blue), or neutral (a mix). Once you know it, makeup, jewelry, and clothing colors stop being a guess. The 4 tests: vein color, jewelry preference, white vs cream draping, and how you tan.
What undertone actually means
Undertone is the color under your skin's surface. It doesn't change with a tan or a fresh face. It's there for life.
Three categories:
- Warm: yellow, peach, or golden underlying tones
- Cool: pink, red, or blue underlying tones
- Neutral: a mix of warm and cool, or true balance
Knowing yours fixes a long list of small style questions: which lipsticks flatter, which jewelry brightens your face, which white shirt is pure white vs cream, why some red dresses make you glow and others wash you out.
Test 1: The vein test
Easiest, fastest, ~70% accurate.
Look at the inside of your wrist in natural daylight (not warm indoor light, not your phone screen).
- Blue or purple veins → cool undertone
- Green veins → warm undertone
- Both, or hard to tell → neutral, keep going to the next tests
If you're squinting trying to see the color, it's probably neutral.
Test 2: The jewelry test
Hold a piece of silver up to your face, then a piece of yellow gold. Stand in a daylight-lit room. Look in the mirror at which one makes your skin brighter, more even, more awake.
- Silver wins → cool
- Yellow gold wins → warm
- Both look fine → neutral
Rose gold is a wildcard — it works on most undertones, so it doesn't tell you much.
Test 3: White vs cream
Pull out a piece of pure white paper or fabric. Then pull out a piece of cream or warm off-white. Hold each one under your chin one at a time, in daylight.
- Pure white makes you look bright and crisp → cool
- Pure white makes you look tired or grey → warm
- Cream warms up your face → warm
- Cream makes you look sallow → cool
Test 4: How you tan
Think about last summer:
- Tan easily, golden brown → warm
- Tan slowly, olive or bronze → neutral or cool
- Burn first, then tan a little → cool
- Burn and freckle, never tan → cool, often light
Tally your answers
Most people lean clearly one way or the other. About 20-25% are genuinely neutral, and that's its own answer — you can wear both warm and cool tones, just lean slightly toward whichever side scored higher.
What to do once you know
Undertone is the first axis of your color season. Combined with two more (light vs deep, bright vs muted) it gives you your full palette.
- Warm → likely Spring or Autumn
- Cool → likely Summer or Winter
- Neutral → could be any season's "true" or "soft" sub-season
What if you're neutral?
Plenty of people don't land cleanly warm or cool, and that's its own useful answer.
How to tell you're neutral
If your veins read blue-green, gold and silver both look fine, and you tan more than you burn but not deeply, you're likely neutral. The tests come back mixed instead of one-sided.
What to wear if you are
Neutral skin handles a wide range but glows most in slightly muted, balanced shades, like soft teal, rose, or warm grey. Lean gently toward whichever side your tests favored, and skip only the most extreme warm or cool colors.

What's the difference between warm and cool undertones?
Warm undertones have a golden, peachy, or yellow cast; cool undertones have a pink, red, or bluish cast. It's the hue under your skin, not how light or dark you are.
What are the best at-home undertone tests?
Check your wrist veins (green = warm, blue = cool), try silver vs gold jewelry, compare white vs cream fabric, and notice how your skin reacts to sun (tans = often warm, burns = often cool).
What if the tests disagree with each other?
Then you're likely neutral, leaning only slightly one way. Go with the result you get most often, and choose slightly muted colors that bridge both sides.
How does undertone change what I should wear?
Warm undertones glow in golden, earthy colors and gold jewelry; cool undertones in blue-based colors and silver. Glowprint reads your undertone from a selfie so you can shop with confidence.
