Weapon Camouflage

In DMZ, is it possible to grind camos like you can in multiplayer and level up weapons?

I got it a week after unlocking Obsidian. I started playing Plunder while using a double XP token. While I was grinding for Mercury, I completed the Echo Endo Live event in just three days! So if you are looking for the fastest way to get Mercury for a gun, play Plunder, complete contracts, and loot caches. “You are green to get greedy!” —Graves

I got the weekly challenges camo only playing warzone, I also only had 1hr until the new season. AND I GOT IT.

Even tho Black Ops 2 sequel has not been confirmed by Treyarch but since there was a recent update about Theater mode and Emblem editor, I had an actual dream about a sequel that features the old fashion way from BO2 such as Pick 10 system, Season Pass, Weapon Camos for $2, no Battle Pass, no Gunsmith, no bundles, and no U.I. Netflix menu style like MWII & III. Instead Warzone returning, the sequel brought Blackout mode from BO4 making its return and makes it better with Pick 10 system. It was the best dream I ever had last night which I hope next year's COD will be the best one like Black Ops 2

I've purchased the 2021 Tornoto Ultra skin and in game it shows up blue and not purple while on Call Of Duty's Website its purple along with Xbox store. I even tried reinstalling the dlc from the xbox store and it's still blue. I don't know if im stupid or what but please someone help me fix this or tell me how to get the purple im willing to purchase it again
