Overtone is the surface read
Overtone is what you see first on the skin: redness, golden tan, ashiness, olive cast, freckles, or surface warmth. It can change with sun, irritation, lighting, or makeup.
Undertone is the underlying color relationship
Undertone is the way your coloring interacts with color families. Some people look better in warm colors, some in cool colors, and many need a more neutral or muted approach.
Contrast matters too
A color can match your undertone and still overpower you if the contrast is too high or too low. Depth and clarity often matter as much as temperature.
Use clothing tests
Compare cream versus bright white, black versus espresso, silver versus gold, clear red versus rust, and icy blue versus muted teal. Photos in natural light usually reveal patterns better than one mirror check.
Build from what works
Your best palette is practical. Start with the colors that repeatedly make your skin, eyes, and outfits look clearer, then build neutrals around them.
