HOW TO PLAY
Toon Tone is a free color perception game. Each round, a cartoon character\'s color flashes on screen — your job is to recreate it from memory using the color wheel.
SEE THE COLOR
A vibrant cartoon color flashes on screen for 3 seconds. Study it carefully — memorize the exact hue, saturation, and brightness.
MATCH IT
Use the color wheel to recreate what you saw. Click the outer ring for hue, then the inner area for saturation and brightness. Trust your gut!
SEE YOUR SCORE
Your guess is compared to the target using ΔE (Delta E) — a scientific measure of color difference. Lower ΔE = better score. Perfect match = 10,000 points!
WHAT IS ΔE?
ΔE (Delta E) is a standard color science metric that measures the perceptual distance between two colors in CIELAB color space. A ΔE of 0 means identical. Under 5 is barely noticeable. Over 25 is obviously different. Your score: max(0, 10000 × (1 - ΔE/50))

HOW TO PLAY — FAQ
How long does each round take?
About 30 seconds — 3 seconds to memorize the color, then as much time as you need to pick your match on the color wheel.
What is the color wheel?
A circular picker where you click the outer ring for hue and the inner area for saturation and brightness. It feels like painting, not typing hex codes.
Can I practice without affecting my rank?
Yes. Quick mode (5 rounds, multiple choice) is great for casual practice. Only Classic mode affects your main rank.
What happens if I run out of time?
If you don't lock in a color before the timer expires, you get 0 points for that round. The game moves on automatically.
LIMITATIONS
- ⚠️Color appearance varies by screen — an uncalibrated monitor may give misleading scores.
- ⚠️The game measures color memory and reproduction, not clinical color vision deficiency.
- ⚠️Internet connection required — the game runs in your browser and loads character assets.
