So if I wanted to give a hat texture the color of the wearer's faction designated in the uniform_to_faction_colours_table, I guessed I'd have to edit the colour masks. I turned everything green to matched the colors in R/G/B/ 2 in the table, but when I tried to get it ingame, the colours wouldn't show up, only those of the texture. So, I wanna know how to edit colour masks... using GIMP
