You've seen Sonic a hundred times. Now prove you remember the exact shade of their body.
Sonic's body sits at hue 220°, saturation 85%, brightness 80% — a vivid blue. You've seen it countless times on screen, but translating that visual memory into exact HSB values is harder than it sounds.
The game shows you Sonic for a few seconds, then asks you to recreate their body color from memory using HSB sliders. Delta-E measures the perceptual distance between your guess and the reference — a score of 10 means pixel-perfect, 0 means you picked the wrong color family entirely.
Sonic pairs well with other anime characters in the same hue family. Play a few in sequence to calibrate your eye — the blue range reveals itself differently across lighting conditions and saturation levels.
