Zero Cost Paint - Yea!, ty Tim. (paint.data file)
I never use “Aesthetic” items that give no actual benefit, especially if they cost me $$. This mod helps… but I’ll probably still never actually paint stuff 
They have no stringly “functional” purpose, but it’s really useful to colour lines (the belts anyway) when you have several lines sharing a room and zig-zagging next to each other. I guess you could use floors similarly but I don’t myself.
