How to Know If You Have Warm or Cool Undertonesに取り組みたい方へ、役立つ 手順書をお届けします。

Head to a drugstore and grab a true red lipstick—not orange, not blue, just red. Swipe it on your hand or lips. If it looks vibrant and “right” on you, you’re cool-toned. If it pulls a bit orange or clashes, you’re warm. A blue-based red (like cherry) is cool; an orange-based red (think tomato) is warm.

I once thought I could pull off a brick red. Big mistake. It made me look like I’d been crying for hours and then applied lipstick in the dark. Now I stick to berry shades—they’re the cool girl’s best friend. Learn from my tragedy.

Pro tip: Don’t test foundation on your hand. Your hand is a liar. It’s usually a different color than your face. I learned this the hard way when I walked around with an orange hand for a week. Your neck is the real MVP for this test.
