Placement is either horizontal bands down the length or vertical panels around the head, and the choice matters: bands show the whole sequence when the hair is down, panels only reveal themselves when it moves. Each color is a direct dye sitting on pre-lightened hair, so they fade at different rates. Red bleeds first and stains whatever it touches, blue drifts green as it goes, and yellow washes out fastest of the four.

Undertonewarm, cool, neutral. Warm and cool blocks sit side by side here, so no single skin undertone is being matched and the saturation of the blocks against your own depth matters more than warmth.
Starting pointEvery block needs hair lifted to at least a pale yellow, which means full bleach on anything darker than natural blonde, often across more than one session.
UpkeepTop up individual colors every two to four weeks as they fall at different speeds, wash cold, and rotate protein and moisture treatments through heavily lifted lengths.
