How the ToonTone game works

  1. 1

    Look

    A national animal appears. Notice its fur, feathers, or scales — what color are they, really? Each ToonTone challenge picks a different species.

  2. 2

    Tune

    Drag the HSL sliders until the swatch matches. Hue, saturation, lightness — your eye learns the trade-offs. The most popular way to play ToonTone.

  3. 3

    Score

    Get a 0–100 score based on perceptual difference (ΔE in Lab space). 100 means a perfect match — every ToonTone game run ends with a shareable score.

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.

ToonTone FAQ

Is the ToonTone game really free?
Yes. No signup, no paywall, no in-app purchases. The whole ToonTone color game runs in your browser.
Do you collect my data?
No. We don't have a server. Your best scores and ToonTone streak live in your browser's localStorage and never leave your device. No analytics on your guesses.
What does the ToonTone score mean?
It's a 0–100 number based on perceptual color difference (Delta E in CIE Lab). 100 = perfect match, 90+ = indistinguishable to most eyes, 50 = noticeably different, below 30 = clearly off. This is the same color perception test print designers use.
Can I get better at the ToonTone challenge?
That's the point. Designers, illustrators, and colorists typically see their scores climb 30+ points within a week of casual play. Daily ToonTone streaks build habit fast.
What is a color guessing game?
A color guessing game asks you to estimate a color value (hex, RGB, or HSL) by eye. ToonTone Guess is a free browser color guessing game that uses perceptual difference (ΔE in CIE Lab) instead of exact-match scoring, so every guess teaches you something about real color vision.
Does ToonTone work on mobile?
Yes. The whole game runs in any modern browser — phone, tablet, desktop. HSL sliders are touch-friendly and the daily ToonTone challenge syncs across devices via your browser profile, not our servers.
