I'm not familiar with the music, or if this might be a religious consideration, but is there anything from Joseph and the Amazing Dreamcoat? (Is that even the right name? I'm a bit brain fried right now.)
Or maybe something from Godspell? Just cuz there are a lot of colors in the outfits. Stuff from Seausical is also great. Those are just coming to mind because there are a lot of colors in those shows.
