How do I find my undertone?

Check three quick signals: (1) wrist veins — blue/purple means cool, green means warm, both means neutral; (2) jewelry — silver flatters cool, gold flatters warm; (3) sun reaction — burning easily suggests cool, tanning easily suggests warm.

Undertone is the constant color underneath your skin's surface — it doesn't change with tan or season. There are three: warm (golden, peachy, yellow), cool (pink, blue, red), and neutral (a balanced mix).

The vein test is the most reliable at-home method. Look at the inside of your wrist in natural light. If your veins look mostly blue or purple, you're likely cool. If they look mostly green, you're warm. If you see both, you're neutral.

The jewelry test is the second-best signal. Hold a silver piece next to your face, then a gold piece. The metal that makes your skin look healthier and more even is your undertone match — silver = cool, gold = warm, both look great = neutral.

The sun test confirms it. People with cool undertones often burn before tanning. Warm undertones tan more easily and rarely burn. Neutral types do a bit of both.

For final accuracy, an AI selfie analyzer measures undertone from your photo's pixel data — far more reliable than self-tests.

  1. Use natural daylight: Stand near a window or step outside; never assess undertone under artificial light.
  2. Inspect your wrist veins: Look at the inside of your wrist — note whether they read blue, green, or both.
  3. Test silver vs. gold: Hold each metal near your face — pick whichever makes your skin look brighter.
  4. Note your sun reaction: Recall whether you burn, tan, or do both.
  5. Confirm with AI analysis: Run a free AI undertone test for an objective second opinion.

Frequently Asked Questions

Can my undertone be neutral?

Yes — about 25% of people are neutral, meaning they can wear both warm and cool tones, with a slight preference for one.

Does undertone change with tan?

No. Tanning changes your overtone (surface color) but not your underlying undertone.

What if my veins look both blue and green?

You're likely neutral. Use the jewelry and sun tests to identify which side you lean toward.
