Cpone's Legendary Armour Skins got updated to 4.0.0 for Update #198 and it's no longer have an unique menu for content that mod's offer. They are colorful, and looks terrible with OVERKILL's official Outfits that have a white-black negative look. I just made most of them like that, with a little effort.

I used Cpone's icons, cut them because they had no alpha layer, then add Invert effect with 0 Saturation.
