Here’s where people get tripped up. Your hair color doesn’t always match your undertone. A blonde can be cool (think icy platinum) or warm (like honey). A brunette could be ash (cool) or chestnut (warm).
Your eyes are a bit more reliable. Blue, gray, or green eyes with flecks of gold? Often warm. Blue or green with silver or navy flecks? Cool. Brown eyes? You could be either—so use the other tests.
