How the Colorful Door works
A colorful door only lets one specific color through, then reveals the next color it will accept.
It is one of the core obstacles you meet through the early and mid levels, usually alongside plain colored blocks and simple gates.
How to play around it
Read the next color in advance and queue the right block before the door changes.
Like every obstacle in the game, the colorful door never makes a level impossible. Every board can be finished without boosters, so if a route feels blocked, the answer is usually the order in which you clear the other colors, not the obstacle itself.
Where you meet it
The Colorful Door typically starts appearing around Level 240 and stays part of the rotation from that point on. Boards that feature it become more frequent as the level numbers climb.
