Episode 2 - Neon works well as Infra-red, although that doesn't exist on Photoshop to my knowledge. Pretty sweet huh?
This is how to do it.
Say you're working on a MOC of a star wars ship, and you want the whole pic to be neon green.
It's easy, see? Look, there should be a filter sign. Scroll over on top of it. And then easily scroll to Artistic, then click on
Neon Glow. Then change it to the color of choice. I chose green.
