Undertone meaning in one sentence
Undertone is the underlying hue that gives your skin its “temperature” — warm, cool, or neutral — and determines which colors make you look your best.
Undertone vs skin tone: the biggest confusion
Most people mix up undertone with skin tone. Skin tone is how light or deep your complexion appears on the surface. Undertone is the subtle color underneath. That's why two people with the same skin depth can look better in completely different palettes.
| Skin tone | Undertone | |
|---|---|---|
| What it is | Surface depth, from fair to deep | Hue beneath the surface |
| Values | Fair, light, medium, tan, deep | Warm, cool, neutral |
| Changes? | Yes, with sun and season | No, stays the same for life |

- Neutral undertone looks balanced and sits between warm and cool.

If you've ever tried a “popular” color and felt off, undertone is likely the reason.
