That's pretty much how I feel. Use colors like yellow and orange and pink, or whatever, just so there's more variety. This was one of the things that I hated about the Prequels, that everybody had pretty much the same colored lightsabers. I can only picture Jedi using either 1 or 2 (long or short) single bladed lightsabers and the double-ended long bladed lightsabers. But that's it.
