You've seen SpongeBob SquarePants a hundred times. Now prove you remember the exact shade of their body.
SpongeBob SquarePants's body sits at hue 50°, saturation 85%, brightness 95% — a vivid orange. 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 SpongeBob SquarePants 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.
SpongeBob SquarePants pairs well with other classic characters in the same hue family. Play a few in sequence to calibrate your eye — the orange range reveals itself differently across lighting conditions and saturation levels.
