Simple way to mix colors

This game has been destroying my entire being of existence. Anyways, here's a cool thing for mixing colors.

the silly contraption

Here it is! It can be extended (though it will get much larger), it's probably not space efficient but this is for new players to learn if they bored as hell waiting for colors to mix. I hate mixing colors. Pain. (I am using the Shapez Industries mod, but this contraption doesn't require it.)
