I want to make it so on the main menu, the player can pick which colour palette they want. Also can the menu buttons for the colours be colourful or does the menu have to be 2 colours too? So for example, there will be a pick palette part. it'll have 5 buttons. 1. black/white , 2.black/orange etc  can these have their own colours or should i just have black writing?

changing between palettes is aloud as long as there are only two seperate colours at a time. :)
