Only the apprentices wear the famous pure white body paint, and wear a lot of bright colors, but of course you must have already known that :b
So yeah, I do a search on just the word Maiko and what I get back is
1. Avatar fanart of Zuko paired with a side character who happens to be named Maiko
2. Jailbait/Furries with huge boobs
3. ACTUAL APPRENTICE GEISHAS

I am disappointed!
