Free undertone test
Undertone is the constant cast beneath your skin, and it decides half of which colors suit you. Four tests below will place you in about five minutes. Do all four: any single one of them is easy to misread.
Skip the guesswork, use a photoDo these in daylight, near a window, with no makeup on. Indoor bulbs are yellow and will push every result warm.
Look at the veins on the inside of your wrist in daylight, never under a bulb.
Hold gold against one side of your face and silver against the other, bare skin, no makeup.
Drape a pure white fabric under your chin, then swap it for a cream or ivory one.
