Why ToonTone Guess works
Most color guessing games test your knowledge. ToonTone Guess tests your perception. The scoring is based on CIE Lab ΔE — the same metric print designers and color scientists use to measure human-perceived color difference. It's a real color perception test, not a multiple-choice quiz.
Our palette is curated for cartoon-friendly hues: saturated, friendly, distinct in Lab space — every color guessing round teaches you something. No muddy grays, no near-duplicates, no trivia. Just pure color matching.
Everything runs in your browser. Your best scores and daily ToonTone streak live in localStorage. We don't track you, we don't have a server. It's color training, minus the surveillance — a free color perception game the way it should be.
