I'll update the post when i find new information.

This macro correctly calculates and displays the progress towards all 3 remaining color variants.

/run local a,x,g,b,y=0,11152,GetAchievementCriteriaInfo;for i=1,11,1 do _,_,_,y,b=g(x,i);a=a+y;end;print("Dungeons: "..a.."/"..b);_,_,_,a,b=g(x+1,1);print("WQs: "..a.."/"..b);_,_,_,a,b=g(x+2,1);print("Kills: "..a.."/"..b);

Edit: The dungeon tracking achievement did not get a 12th criterion for Return to Karazhan. I would therefore argue that it does not contribute to unlocking the 2nd color tint of your hidden appearance. Good news: the macro is still correct as of patch 7.1; Bad news: you'll have to complete 100 of the initial Legion dungeons.

Macro to track the amount of world quests you still have to complete to unlock the 3rd color variant (Hidden Tracking - Appearance Unlock - Hidden - Color 3 (update criteria when world quests available)):

/run AddTrackedAchievement(11153)
