Apologies for the late reply, but lately the team and I have considered being able to change the color of both yourself and your weapon. Changing your color changes elemental type and a few basic moves, while changing the color of your weapon changes your stats and gives you additional moves that play into the stat buffs you gain. For instance, if you want to be blue but deal high damage, switch your weapon to red and your color to blue and use the blue moves that come with changing your color. Have yet to actually try this but I'm liking the sound of it.
