Wear colors that flatter your skin undertones. Your skin undertones will be either cool, warm, or neutral. Cool undertones are pink, red, or bluish, warm undertones are yellow, peachy, or golden, and neutral undertones are a mix of both. To find your skin tone, look at the veins on your arm to see if they’re blue, which means cool, or green, which means warm. Alternatively, hold gold and silver jewelry against your skin because gold jewelry looks best on warm tones while silver looks great with cool tones.
