I made this game; in case anyone's wondering how the scoring works: It draws your version over the original with 'difference' compositing, then downscales the result (using 'medium' quality to avoid most pixels getting skipped) and adds up the R, G & B values for every pixel in that small image. This total is then compared with the total difference for the initial state (which represents 0%). Darker areas have the bi…

Fun! What did you implement it with?

It's just simple HTML/CSS/JS and canvas manipulation; scoring is done using 'difference' compositing & checking pixel RGB values, and brushes are built up from bog-standard canvas strokes.

78% with just 4 color bars.

Super fun game.

Problem is, I got a 78% score with just 4 horizontal color bars.

Just filling in the canvas with black gets you to 75%, then you can add some green and yellow to get to 76% but after that it seems you need to be more precise to get higher.
