This is the most famous trick—and it’s not just an internet myth. Look at the inside of your wrist in natural light. Are your veins more green or blue? If they look green, you’re likely warm (hello, golden undertones). If they appear blue or purple, you’re probably cool (think rosy or pink).
Now, here’s the ironic part: I have a friend who swore she saw both colors, so she panicked and bought every foundation shade ever made. (Spoiler: she’s neutral, which is totally a thing. More on that later.) Trust your first instinct—don’t overthink it.
The White Paper Trick (Seriously, It Works)
Grab a plain white piece of paper and hold it next to your bare face in daylight. If your skin looks yellow or peachy against the white, you’ve got warm undertones. If it looks pink or bluish, you’re cool. If you can’t tell, and your skin just looks… skin-colored? You’re probably neutral, which is basically the “I win at life” category.
Funny side note: I did this with my mom once, and she got so frustrated she threw the paper at me. She’s cool-toned, if you couldn’t guess. Don’t let it become a family drama—keep it simple.
