I might be confused, but doesn't fire normally change colors depending on what it's burning and how hot it is?
Though it might be silly to make fire different colors for different substances, I'm wondering if it might be possible to make fire blue as it first starts out (presumably as hot, since it would begin at its default temperature and then cool down... Right?), and then range down to orange, or... I don't know, but you know what I mean. xD
Does anyone know what combinations might be useful/cool-looking for this particular game?
As SerGreen said, it's not really useful. The fire does change color at different temperture but I think it would slow down the game for pretty much nothing. But that was smart thinking.
