If you want make a real sick job. Add the color of the Secondary resource needed for the armor.
Example Silk is gonna be white. Iron Silk is Grey white Blue.
it add a lot of visual customization for player and detail of the armor ( You can visually conclude that the armor is made of Flake and Silk).
I dont think its a priority for MO tho ..Weapon Color is way more needed than the Armor.
( I just wonder there is 3 Color. The Brown Dark (leather) Look fine. The Light brown should be change. hf)
