Is there anyway you can change the color of a flame?
If yes, how?
If yes, does it cost?
If yes, is there a limit of how many times?

Well, I am unsure if there is a specific way to do it but I had a flame, I forgot the name, I simply used a Particle texture and experimented with colors. I think a Purple image on the Particle texture was green on the flame, so I would just say experiment with a particle texture.

Again, I am unsure and there is probably a much simpler way



EDIT: Or if your not broke do what Omega says ;o

just buy a whole 'nother flame.or draw another flame texture.

okay here is how you change the color of void flames only:

1. get a fpt (duh)
2. okay this is tricky. lets say you want a plain black flame color. what you do is invert the color of the color you want.

ex: black flame = white fpt, static yellow flame = dark blue fpt and so on
