Making the color of particles change as they become older

Hi guys!

I’ve been working on a Pulsar Simulation for some while now, and you may have already seen me flooding each of the other sub-forums with questions :stuck_out_tongue: But more the doubts, more you learn, right?

I wanted the particles to go from a warm yellow-red to cold blue as they get farther from the star. Is there some compositor node I can use? And if so, then what do I do?

PS: Please move this thread if it is in the wrong section

Ah thanks for that! Cheers. Maybe next time I should do a bit more googling…
