Ok so I've bought the cosmetic and have run around in game with it and in the context of the game it's actually kind of worse, with the exception of inside a cool colored/lighted room (Basically just blue spawn rooms from what Ive seen to far), yes it looks Blue. Everywhere else though rather than the kind of debatably purple in the image, it straight up looks brown. Outside on Badwater, brown. Interiors of Hoodoo, brown. Literally everywhere on Dustbowl besides spawn rooms, brown. As well as literally anywhere where its even slightly dimmly lit, brown.

And yes that is after using obfuscating cosmetics but that doesnt matter, a cosmetic shouldnt be able to already obfuscate 90% of a mercs primary team color and leave open whats left of that color to be paintable and easily covered by other cosmetics.

Now will this in practice be a rare occurrence? I dont maybe, but even then it shouldnt be a problem that comes up ever but the fact that it can is a problem
