Download Mario Learns About Colors
Mario Learns About Colors is an interesting platformer with a lot of educational elements that your child may benefit from if you allow him to play the game. The game features a lot of different levels in which you will have to change Mario's color in order to get him through different sections of the level.
The game is similar to Crillion in terms of color changing and so on but it seems to be much better than that kind of game and you might enjoy it better. The game might even allow you to mix certain colors in order to create new ones.
