Toon Tone

Toon Tone is a free online color guessing game where players match cartoon character colors using HSB sliders, scored by perceptual color difference.

What is Toon Tone? Toon Tone is a web-based game that challenges players to reproduce a specific character's color (e.g., hair, outfit) using hue, saturation, and brightness sliders. The game displays a cartoon character image with a translucent target area; adjusting the sliders changes that area's color. Each round presents a target color from a character (e.g., Roronoa Zoro's green hair from One Piece) and the player's guess is scored using CIEDE2000, a perceptual color difference formula. The game is built and updated independently (Toon Tone Pro) and requires no account or login.

Key Features - HSB Slider Controls — Tune hue (0–360°), saturation (0–100%), and brightness (0–100%) independently without typing color codes. - Perceptual Color Scoring — Each guess is scored via Delta E (CIEDE2000), converting perceptual difference into round points. - Growing Character Library — New cartoon images and target areas are added over time, expanding the round pool. - Themed Editions — Curated round sets for specific universes: Pokemon and SpongeBob, with more in development. - Immediate Feedback — After submission, the game shows round score and a visual comparison of your selection vs. target color. - No Download Required — Runs entirely in the browser; no installation, signup, or login needed.

Who is it for? Toon Tone is designed for casual gamers who enjoy visual puzzles, fans of anime and cartoons wanting to test color recall, and anyone curious about color perception. It is beginner-friendly and requires no art skills—just a willingness to match hues by eye.

What can you do with Toon Tone? - Test your color perception: Attempt to match character colors exactly using the HSB sliders, then see your perceptual accuracy score. - Play themed challenges: Choose from Pokemon or SpongeBob editions for rounds focused on specific character palettes. - Track improvement: As the library grows, repeat rounds with new characters and see if your color sense improves over time.

How does it work? Each round begins with a character image and a labeled color area (e.g., "Roronoa Zoro's Hair"). Players adjust the three HSB sliders until the overlay color matches the original shade. After submitting, the game calculates the perceptual difference using CIEDE2000 and displays a score (0–1000, with higher being better). The game then shows the target color alongside the player's selection for visual comparison.
