Do you have spare time? Do you want to do something relaxing? Perhaps you want to grind some easy achievements? Or maybe you're just waiting for a video to load. It doesn't really matter because with Colouration you can play the game and do all that at the same time!
In Colouration all you have to do is fill out the randomly coloured grids by clicking the dimmed out squares. By filling out the entire grid, you will be able to advance to the next level where you will do the same thing (just on a different grid). From there: rinse and repeat.
Colouration gives a laid-back and satisfying experience so if you're a casual player (or a competitive player who's on a break), then this is the game for you.
