Hidden Tracking - Appearance Unlock - Hidden - Color 4

once you have obtained a hidden skin, ya can use this macro to check your progress
/run local q,x,_,a,b = GetAchievementCriteriaInfo,0 for i=1,11 do _,_,_,a,b = q(11152,i) x=x+a end local _,_,_,c,d = q(11153,1) local _,_,_,e,f = q(11154,1) print("Dungeons: "..x.."/"..b) print("WQs: "..c.."/"..d) print("Kills: "..e.."/"..f)
the format it prints in your chat box, with your current progress:
Dungeons: 0/100
WQs: 0/200
Kills: 0/1000

------ ---- -- ---- ------

You can use these macros to actually visually track completion progress

200 WQs Hidden Tracking - Appearance Unlock - Hidden - Color 3 (update criteria when world quests available)
/run AddTrackedAchievement(11153)
1000 PKs Hidden Tracking - Appearance Unlock - Hidden - Color 4
/run AddTrackedAchievement(11154)
100 Dungeons Hidden Tracking - Appearance Unlock - Hidden - Color 2
/run AddTrackedAchievement(11152)

I've created a single macro to track dungeon, world quest, and player kill progress.
/run local a={Dungeons=11152,WQs=11153,PKs=11154}for b,c in pairs(a)do local d,e=0;for f=1,GetAchievementNumCriteria(c)do local g,h=0;g,g,g,h,e=GetAchievementCriteriaInfo(c,f)d=d+h end;print(b..": "..d.."/"..e)end

This macro will output something similar to:
PKs: 0/1000
WQs: 0/200
Dungeons: 0/30

Additionally, you can track these hidden achievements.

30 Dungeon Completions (final boss kills) Hidden Tracking - Appearance Unlock - Hidden - Color 2
Keep in mind that dungeons are tracked individually, and the sum of all of the dungeons is what counts for the achievement.
/run C_ContentTracking.StartTracking(2, 11152)

200 World Quests Hidden Tracking - Appearance Unlock - Hidden - Color 3 (update criteria when world quests available)
/run C_ContentTracking.StartTracking(2, 11153)

1000 Player Kills (of any kind) Hidden Tracking - Appearance Unlock - Hidden - Color 4
/run C_ContentTracking.StartTracking(2, 11154)

Please let me know if this helps you out!

Edit: I condensed the macro and included [zone=8443] (and any future dungeons).
Edit 2: Updated achievement tracking code and reflected new 30 dungeon requirement (down from 100).

Not sure if this needs to be said, but Comp Stomp will NOT count towards the 1000 player kills needed for this hidden artifact tint/achievement.
