Toon Tone

Toon Tone (toontone.fun) is a free cartoon color guessing game you play in the browser. Each round shows a cartoon character with no reference color, and you drag Hue, Saturation and Brightness sliders to rebuild its signature shade from memory. Lock in your guess and the game reveals the true color and scores your accuracy and time. There is a fresh daily lineup of five characters and an Easy Infinity mode for endless practice. The site also offers its own free color games — Hue Sort, Odd Hue, Hue Mixer and Liquid Hues — and a comparison of 13 color games. Works on desktop and mobile; no download, sign-up or account.
