Did you not read @O Ilusionista's post?Question: How do you select the color since the cursor can move in four directions? Do you select the template first, then the color at the top and bottom? Is it possible to undo the selection?
It's also in the video too - the commands are shown on screen at the top. Color cycling is mapped to Attack / Jump. The fact you asked this question is exactly why I chose those two buttons. So players will discover it by accident when they habitually press Attack.
It would be possible to have an undo, but also add to the complexity for not much benefit since the engine already lets you back out of selection with the Escape key.
