Flip your wrist over and look at your veins in natural daylight. If they look blue or purple, you’re likely a cool undertone. It’s like you have a little river of blueberry juice under there.
If they look green, congratulations—you’re warm. Your veins are basically chameleons, mixing blue and yellow. And if you’re staring, squinting, and still can’t tell? You might be neutral, the unicorn of undertones.
The White Paper Trick (No PhD Needed)
Grab a piece of plain white paper and hold it next to your bare face. If your skin looks pinkish or peachy next to the white, you’re cool. If it looks yellowish or golden, you’re warm.
If your skin just looks kind of gray or meh? That’s your neutral undertone playing hard to get. This works best with no makeup on, and maybe after you’ve had your morning coffee—because we all look a little gray before caffeine.
