Why HSB sliders
Hue, saturation, and brightness match how people talk about color. You can decide whether a remembered toon color is warmer, more muted, or darker without thinking in RGB math.
How Toon Tone scoring works
Toon Tone turns your HSB slider guess into a hex color, compares it with the target shade using perceptual Delta E distance, then maps that distance to a 0-100 round score.
Try a scored roundWhy Delta E
Delta E measures how different two colors look to human vision. A small visual miss can score well, while an obvious color-family miss drops quickly.
Why the API recalculates scores
Leaderboard saves send only the seed and HSB guesses. The server rebuilds the challenge and recalculates every score before storing the entry.
