Custom aura colours
Thinking about the high demand to add colourblind settings, why not just add a custom aura?
Aside from helping people actually see gens etc, I think it would be a cute little addition to the game to be able to choose whatever colours you want. Its a little silly to say, but I like the idea of logging into the game and thinking "hm, what colour do I want kindred to be today?" Or if you're colourblind you can make it the most visible colours possible
