The emitter holds the light and particle system that you want to change the color on. You will have to modify the particle system to have the “Color” parameter though since the particle emitters in the default “StandingTorch” particle system don’t have paramters setup. Make a copy of the emitter and particle system. Link the copied particle system in the copied emitter bp and then link the new emitter in your wall torch. In you particle system you want to change the “Distribution” of the “ColorOverLife” module to “Vector Particle Parameter” on the two fire emitters and the smoke emitter(or more if you want to) in the particle system and assign the name “Color” to it.
You can then do this in the graph to assign any color you want:
