Hey — Sam here, solo dev behind Toon Tone ( https://toontone.app ). # The pitch in one sentence You see a cartoon character with one body part whitened out. You drag H/S/B sliders until your color matches the one you remember. Five rounds, scored 0–10 per round by how close you got. # Why this exists We all "remember" cartoon colors — SpongeBob's yellow, Pikachu's cheeks, Mario's red — but the moment you reach for a color picker, you realize your memory is off by 30, 40, even 60 RGB units. That gap is the whole game. # Three design decisions I want to talk about ## 1. HSB sliders, not RGB RGB sliders are a UX trap. Pushing "more red" doesn't feel like pushing toward what your brain thinks "more red" is. HSB matches human color intuition — hue is "which color," saturation is "how vivid," brightness is "how light." Players adjust hue first, then saturation, then brightness. That's how memory works too. ## 2. sRGB Euclidean distance for scoring I know — it's not perceptually uniform.…
