Colours is a co-op and single player map pack for Portal 2 which features custom textures, sounds, and a whole lot of fun puzzles which focus entirely on synesthesia, puzzle solving, and cooperation. Features custom music, sounds, and more. Each map will be released as it is completed in order creating a chronologically episodic release, where each map will link to the next and if it does not then it simply resets.
[UPDATED]: Now contains a version for computers with less RAM! Also made slightly easier :D The hardest-greenest chamber yet!! This links to all previous Colours maps as well as Colours 4 in the future.
