I recently discovered, hat you can give the color of shaders values higher than 1. If you seperate a color in it’s individual values, multiply it and combine it again, this can be use to give them a nice fake glowing effect that works for every shader and looks sweeter then just mixing it with Emission. Sure it’s not working without any light because 0*x still is 0.
here are some other examples with glass, glossy, hair and absorption shaders:
i hope some of you might find this usefull
