Trying to update this myself and having issue with changing the colors on the icons as now there is a green belt in the base game I'm trying to change the green one, but damn, I have no idea how to do that and make it look good.
How the heck did the author make all new colors of tech and craft icons without destroying the rest of the image? Any tips out there? I can't find a way to efficiently isolate the color part of the icons.
