What is the best hair color for cool undertones?
Cool-undertone skin (pink, red, or blue undertones) is flattered by hair colors in the same temperature family: ash brunette, mushroom brown, ash blonde, platinum, cool burgundy, and jet black. Warm tones (honey, gold, copper, caramel) tend to read brassy against cool skin.
The rule of thumb for hair color and skin undertone is to match temperatures. Cool skin (pink or blue undertones) reads cleanest against cool hair colors. Ash variants (ash brunette, ash blonde) and any color with grey, blue, or violet undertones flatter cool skin reliably. Mushroom brown is the most-requested cool-toned brunette of recent years for exactly this reason.
The deepest cool tones (espresso brunette, jet black, cool burgundy) flatter cool undertones particularly well because the high contrast with pink skin photographs sharply. Platinum blonde is the lightest end of the cool-tone spectrum and is one of the most photogenic options for cool skin, though it requires high maintenance.
Warm hair colors (honey blonde, copper, caramel, golden brunette) are technically the opposite of what flatters cool undertones, but a skilled colorist can still make them work with the right tone-down at the root. The Color Analysis tool reads your undertone from a selfie and tells you which color family flatters you before you commit to a salon appointment.
