LOGIC OF THE HIDDEN COLOR

       




Desktop Java Applet

In the desktop version of the game you need to use the color picker on the right to mix your guess.
Press 'Show' when you think you're done.
The hidden color will appear next to your guess, and you will be able to compare them.
Your result will be caclulated on an accuracy scale*, and the smaller number you get, the better.

*The similarity between two colors is calculated by placing them in a three-dimensional color space.
The accuracy scale number is the distance between the hidden color and your guess.
