I did read your note; the rainbow room I see in Cloning Technology is really the Lab background.
To enable it, in a room with the Lab tileset, set the mode to either manual or multi (not auto), then cycle through the colors until it says Rainbow BG.
Thank you, I will figure out how to enable manual or multi mode through that Documentation that (I hope) you made.
Oh, and I did know that was the Lab tileset because of the background.
Can I say something, is it possible to make the tileset change color too?
Or is it just impossible?
Edit: I also wanted to know if there is a script command that can change the room color.
