ToneGuess is a free browser-based color memory game.

It's a fun way to test how well you perceive and remember color.

Each round is scored from 0.00 to 10.00 based on the difference between your guess and the target color in RGB space. The closer your color, the higher your score. A perfect 10.00 means you matched it exactly. Using the hint feature subtracts 1 point from that round.
Each game has 5 rounds. Your final score is the average of all 5 rounds. A 9.00+ average means you have an excellent color memory!
