You've seen Squirtle a hundred times. Now prove you remember the exact shade of their shell.
Squirtle's shell sits at hue 205°, saturation 70%, brightness 75% — a vivid cyan. 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 Squirtle for a few seconds, then asks you to recreate their shell 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.
Squirtle pairs well with other anime characters in the same hue family. Play a few in sequence to calibrate your eye — the cyan range reveals itself differently across lighting conditions and saturation levels.
