Margie’s playing around with this in Beta. There’s a full screen in the character creator where you can control the colors of the various powers — by power, by power set, or for all your powers.
Many of the powers, though, in addition to the power color itself, you can create a bright or dark option — or, in some cases, turn off the effect entirely.
So no more Regen Scrappers running around with green starbursts in their chests. They can be running around with no effect, or something much more subtle. Tired of your duo partner’s ice armor buffs making your costume impossible to see? Voila, the ice effect is much more subtle. And, maybe (not yet tested) you can do Invuln characters that are not all Dark or Shiny.
You can also save configurations for the Primary, Secondary, or all power sets, so you can play with effects between characters still better.
Oh, and while there are still name-per-server limits, there’s now a Check Name button on the ID card screen, and you can hop there first, just to try names out.
Win.
