It's not a technical problem, but it's still a problem. I want it to look right, so I don't want to just use false color and mess with the wavelengths. I don't want bullets to turn invisible when they come at you too fast. For now, I just have it show some minimum color if it shifts out of the visible spectrum, or even if it's just black. I don't want to do that in the actual game, though. I'm thinking of giving stuff colors outside the visible spectrum, and maybe just making most of the enemy bullets infrared.
