Why HSB sliders
Hue, saturation, and brightness match how people talk about color 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, so obvious color-family misses drop quickly.
Why the API recalculates scores
Leaderboard saves send only the seed and HSB guesses. The server rebuilds the challenge and recalculates every score.
