The gloss function uses a texture from the seventh installment of the game, created by the developers, and there are no specific standards for it (everyone did it as they saw fit; for example, the crossbowmen-veterans have a texture with yellow hues), and I'm too lazy to redo them.
Well, you can recolor it later... because it reflects light too much!
