blue" is another game in the series of color games from the developer Bart Bonte. In each of the fifty levels, we need to color everything in the shade of blue. For this task, we will need to strain our brains, as each level has its own logic for coloring the map. After coloring the first level, you can continue coloring, or you can leave and start again from the same place later. Can't figure out how to color everything in the colors of the oceans and skies? Take a hint that will help you solve the puzzle of blue and other colors that shouldn't be there.
