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.…
