Crowley Astray

Ok, I'll try it right now, thanks Edit: It's working great! There are loads of useful features in there, thanks for sharing

Hello everyone, and thanks for reading in advance! Firstly, I am not sure if my title is accurate at all; I am not very fluent with the expressions of this jargon as I am only just getting into it (sorry for any possible confusions caused by it) Example of what I am trying to do (this is just a generic example and I did NOT create the art): I would, in this example, want to recolour the lightsabre blue. What I'd also need to do, is changing the red light that is projected on his armour into a blue one. I'd use it to change already existing art, mostly created by myself, which I don't want to redo altogether as that would take a lot of time. I'd hope for someone to post a link to a tutorial to solve this problem, as I myself wasn't able to find an appropiate one, so sorry for that. Have a nice day ~Crowley PS.: The art is created by Gregory Parkin, you can find him here: https://www.behance.net/GregoryParkin
