Undertone is the color direction produced by the pigment composition beneath your skin’s surface — independent of how light or dark your skin is. It determines which foundation shades, jewelry metals, and clothing colors work best for you. For the full science and warm/cool/neutral comparisons, see the Undertone Complete Guide.
Set Up for an Accurate Result
The most common reason self-tests fail is lighting. Get these conditions right before you start.
Key reminder: Light skin ≠ cool undertone. Dark skin ≠ warm undertone. Brightness and undertone are completely independent variables.
How to Use Your Result
Warm undertone → Gold jewelry · ivory/cream white · yellow-base foundation · coral and peach lip shades
Cool undertone → Silver or white gold jewelry · pure white · pink-base foundation · berry and rose lip shades
Neutral undertone → Both gold and silver work · ivory and pure white both suit you · widest range of color options across the board

FAQ
Q. My result came back neutral — does that make color selection harder? Actually, it’s an advantage. Neutral undertones are compatible with both warm and cool palettes. Gold and silver both work, and you have the widest selection of lip, eye, and clothing colors.
Q. My tests gave conflicting results — what do I do? Run 3 or more tests (veins, metal, white paper, clothing) and go with the majority result. If results are split evenly across warm and cool, neutral is the most likely answer. More on the method: Undertone Complete Guide →
Q. Can jaundice or liver conditions affect my result? Yes. Elevated bilirubin in jaundice causes a yellowish cast that can register as warm undertone. If your health status has recently changed, retest after recovery.
