How to Find Your Skin Undertone (Cool, Warm, or Neutral)

Surface tone is how light or dark your skin looks and it can change with sun exposure. Undertone is the constant hue beneath the surface — cool (pink, red, blue), warm (yellow, peach, gold), or neutral (a balance of both).

Undertone, not surface tone, decides whether gold or silver, ivory or pure white, coral or berry look right on you.

Vein test: in natural light, greenish veins on your inner wrist suggest warm; bluish or purple suggests cool; a mix suggests neutral.

Jewelry test: warm undertones usually glow next to gold, cool undertones next to silver. Whichever makes your skin look brighter is your match.

White vs cream: hold a pure-white item and an ivory item near your face. If cream flatters, you likely lean warm; if bright white wins, you likely lean cool.

Sun test: skin that tans easily and rarely burns leans warm; skin that burns first often leans cool.

Indoor bulbs add yellow and screens add blue, which can flip your reading. Always judge undertone in soft, indirect daylight near a window.

This is exactly where an AI analysis helps: it evaluates skin, hair, and eyes together and is less fooled by a single lighting cue than the eye is.
