In theory this should bug around 10% of the males playing the game.
I wasn’t even aware that there was an “out of range” indicator under the action bar buttons until it was mentioned in a chat window. Basically Red against any dark color is a horrible combination because it might as well be invisible.
I haven’t got far enough into the game to tell if there is a “Blue” vs “Purple” type problem that WoW had for many years. Some ability to configure the colors for the UI would be greatly appreciated.
