Toon Tone is a free browser game about color sense, not color codes. Each round shows a cartoon character with a target color area, and you match it by eye using hue, saturation, and brightness sliders.
Scoring uses CIEDE2000 — a perceptual color-difference formula — so you are graded on how close the match looks to a human eye rather than how close the raw numbers are. New characters are added regularly, and there is a Daily Challenge alongside a rolling 7-Day Tone Legends leaderboard. Themed variants cover Pokémon and SpongeBob.
Key Features
- HSB slider controls — Fine-tune hue, saturation, and brightness by hand.
- CIEDE2000 scoring — Perceptual color accuracy, not numeric distance.
- Daily Challenge — A new round every day.
- 7-Day Tone Legends leaderboard — Rolling weekly rankings.
- Themed variants — Pokémon and SpongeBob editions.
- Growing character library — Fresh rounds added regularly.
Who It’s For
Designers who want to test their eye, cartoon fans, and anyone after a short skill-based browser game that does not need an account.
How It Works
- Look at the cartoon character and the highlighted target color area.
- Adjust the hue, saturation, and brightness sliders until the color matches.
- Submit your guess and get a score based on perceptual color accuracy.
Toon Tone is free to play, with no account, login, or download required.
