Undertone, Value & Chroma
The three axes that explain why some colors make you look alive and others make you look dead.
Grounded in the research on personal color analysis
Map your undertone first
Your skin's undertone is the dominant hue cast beneath the surface — warm (yellow/gold/peach), cool (pink/red/blue), or neutral. It doesn't move with a tan. Check the inside of your wrist in natural light: green veins = warm, blue/purple = cool, both = neutral. This single axis determines whether gold or silver jewelry makes your face look awake or washed out.
Learn the value axis
Value is lightness versus darkness on a grayscale. Johannes Itten's 1961 color sphere at the Bauhaus formalized this: high value = pale, low value = deep. Your hair, eyes, and skin sit somewhere on that axis — your 'overall value.' Wearing colors far outside your natural value range creates visual noise. A deep-toned person in pastels looks washed. A light-toned person in heavy charcoal looks overwhelmed.
