I had this idea and I wanted to do a mockup, so here we go

Rainbow (normal):
Note: I might swap the order of the colors so the neon green is on the outside because it looks slightly derpy



Forest (dark brown):



Pastel (light pink):



Royal (purple):



Neon (neon red):



If you don't support please tell me why!
Also if you have a color palette suggestion let me know and I might try it out! :3
