Knowing your skin undertone is the key to choosing flattering colors — from makeup and clothing to hair color and jewelry. But figuring out whether you're warm, cool, or neutral can be surprisingly tricky. This quick undertone test walks you through five reliable methods you can do right now, at home, with things you already have.
The best approach? Try all five tests and see which result comes up most often. If you get mixed answers, you're likely neutral — and that's not a bad thing. It means you have the widest range of flattering options.
What Is Skin Undertone?
Your undertone is the subtle color beneath your skin's surface. Unlike your skin tone (which can be fair, medium, or deep and changes with sun exposure), your undertone stays the same for life. It's determined by the balance of melanin, hemoglobin, and carotene in your skin.
- Warm undertone — golden, yellow, or peachy hues beneath the surface. You look best in earthy, warm colors.
- Cool undertone — pink, red, or bluish hues. You look best in jewel tones and blue-based colors.
- Neutral undertone — a balanced mix of warm and cool. You can pull off colors from both families.
Test 1: The Vein Check
Look at the veins on the inside of your wrist under natural light (near a window, not under fluorescent bulbs). This is the fastest undertone test and takes about 10 seconds.
- Green veins → warm undertone. Your skin's yellow pigment combines with blue blood to look green.
- Blue or purple veins → cool undertone. Your pink-toned skin lets the blue show through clearly.
- Both green and blue → neutral undertone. You see a mix of colors without a clear winner.
This test works best on lighter skin tones where veins are clearly visible. If you have deeper skin and can't see veins easily, skip to Test 3 or Test 5.
Test 2: The Gold vs. Silver Jewelry Test
Hold a piece of gold jewelry against one wrist and silver against the other. Look at which metal makes your skin glow versus which makes it look dull or grayish.
- Gold looks better → warm undertone
- Silver looks better → cool undertone
- Both look equally flattering → neutral undertone
Important: focus on which makes your skin look healthier, not which jewelry you prefer aesthetically. Many people have a personal preference for silver but actually have warm undertones (or vice versa).
Test 3: The White vs. Cream Fabric Test
This is the test professional color consultants rely on most. Hold a piece of pure white fabric and a piece of cream/off-white fabric against your face in natural light. One will make your skin look healthy and radiant; the other will make you look washed out, yellowish, or tired.
- Pure white is more flattering → cool undertone
- Cream/off-white is more flattering → warm undertone
- Both look fine → neutral undertone
Don't have fabric? Use two pieces of paper — one bright white printer paper, one off-white or cream. Hold them near your jawline and compare the effect on your skin.
Test 4: The Sun Reaction Test
Think about how your skin reacts after spending time in the sun without protection. Your natural response offers clues about your undertone.
- You tan easily to a golden or olive brown → likely warm
- You burn first, then tan slightly or not at all → likely cool
- You tan to a neutral brown without strong golden or pink tones → possibly neutral
This test is the least reliable of the five — sun sensitivity is influenced by many factors beyond undertone. Use it as a tiebreaker, not as your primary method.
Test 5: The AI Photo Analysis Test
Technology has made undertone determination far more accurate than DIY guesswork. AI analysis works by measuring actual color values in your skin from a photo, removing the subjectivity that makes self-assessment unreliable.
HueCheck's AI undertone test uses the same fabric draping methodology that professionals use — you photograph yourself holding white and cream fabric — but the AI analyzes the results objectively. It measures subtle hue shifts that are difficult for the human eye to judge on its own skin.
Studies show that about 40% of people misidentify their own undertone using DIY methods alone. The main culprits are artificial lighting, existing tan or sunburn, personal color biases, and the inherent difficulty of objectively evaluating your own face.
How to Score Your Results
After completing all five tests, tally your results. The undertone that appears most often is almost certainly correct.
- 3+ tests point warm → you're warm-toned. Your best colors are gold, olive, coral, peach, cream, warm red, and camel.
- 3+ tests point cool → you're cool-toned. Your best colors are silver, navy, fuchsia, plum, icy pink, emerald, and pure white.
- Results are split or you got 'neutral' on multiple tests → you're neutral. Lucky you — you can wear most colors from both warm and cool families.
What to Do Next: From Undertone to Color Season
Your undertone is the first piece of the puzzle. To get your complete personalized color palette, you need two more data points: your value (how light or dark your overall coloring is) and your chroma (how bright or muted your features are). Together, these three characteristics determine your exact color season out of 12 possible sub-seasons.
Warm undertones place you in the Spring or Autumn family. Cool undertones mean you're a Summer or Winter. From there, your value and chroma narrow it to one of three sub-seasons within that family — giving you a precise palette of 50+ colors that are specifically calibrated to make you look your best.

Common Questions About the Undertone Test
Can I take this test with makeup on?
No — always remove foundation, concealer, bronzer, and blush before testing. These products alter your surface color and can completely mask your natural undertone. Bare, clean skin gives the most accurate results.
Does my undertone change if I get a tan?
Your undertone never changes. A tan darkens your surface skin tone but doesn't alter the underlying warm, cool, or neutral hue. However, a heavy tan can make it harder to see your undertone clearly — so test when your skin is closest to its natural state.
I have dark skin — which test works best for me?
The white-vs-cream fabric test (Test 3) and AI analysis (Test 5) tend to be most accurate for deeper skin tones. The vein test can be unreliable if veins aren't clearly visible, and the sun reaction test doesn't differentiate well across all skin depths.
What if I'm neutral — does that mean color analysis doesn't apply to me?
Not at all. Neutral undertones still have a slight lean toward warm or cool. A full 12-season analysis can detect that lean and place you in the right sub-season. Neutral undertones often land in 'border' sub-seasons like Soft Autumn (warm-neutral) or Soft Summer (cool-neutral).
