About ToonTone Guess

A free browser color perception game that runs entirely in your browser — no signup, no tracking.

Why a ToonTone color game

Designers, illustrators, and colorists develop their eye through deliberate practice — not by staring at color wheels. ToonTone Guess gives you a daily, fast, low-pressure way to train color recognition and hex intuition, without the surveillance or paywalls of most "creative" tools. It is, simply, the best color guessing game you can play without an account.

How the color perception test works

Each guess is converted to CIE Lab color space and compared to the target via ΔE (CIE76) — the same metric print designers and color scientists use to measure human-perceived color difference. We map ΔE → 0–100 score with an exponential curve: perfect match = 100, ΔE=1 ≈ 92, ΔE=10 ≈ 43, ΔE>50 → 0. This makes the ToonTone color perception test rigorous but forgiving — exact hex matching isn't required, only perceptual closeness.

The ToonTone palette

40 saturated, cartoon-friendly colors curated to be distinct in Lab space — no near-duplicates, no muddy grays. Each color has a real name (Cherry Red, Mint Pop, Electric Violet…) because naming colors is itself a form of attention. The ToonTone game palette doubles as a color matching quiz reference: if you can name a color, you can usually reproduce it.

Color training for designers

Whether you're a graphic designer, an illustrator, a colorist, or just someone who wants to sharpen their eye, ToonTone Guess is built for the kind of rapid, repeatable color training professionals rely on. Designers often report a 20–40 point score jump within a week of daily play — the same perceptual calibration taught in art-school color theory, condensed into a 60-second browser game.
