Randomly Colored Fire option for the Fire effect

The Idea

Randomly Colored Fire option for the Fire effect just like with compiz: https://www.youtube.com/watch?v=kJfBPLtyRS4 (couldn't find a video showing a more recent version of that effect since it looks even better than that one)

Hi there! Thanks for the suggestion! So the idea would be to have a colorful (very magical) fire? In Compiz times, the fire was a particle system and - judging from the video - each particle seems to have gotten a random color. Adding a similar effect to Burn-My-Windows could be done with three additional noise function evaluations (one for the red, green, and blue component of the magic color), I think.

As soon as I have the time, I'll try this. If anyone wants to work on this in the mean time, just drop a note here so that we do not work on it in parallel!
