City of Heroes was designed in such a way that power customization would be very difficult. So a recent forum post hinting by lead designer Matt "Positron" Miller showing that it's apparently happening makes this news all the more interesting.
Of course, all we get are a couple screenshots of purple and blue imps to tease us, but then again what else do you really need to know right now? Well okay, we suppose you could know how colorization works and if it's something that's done only during character creation or at any time while playing. It would also be nice to know the extent that powers could be customized, too.
We'll just have to wait until July to hear more about Issue 16. So until then, dream about City of Heroes in whatever color you like -- even made up ones!
