After looking at a lot of photos of people with their faces painted I've come to the conclusion that it looks pretty dumb on most of us (kids and rock stars excluded even though they look creepy most of the time too). The lucky few who can pull it off:
Models. Best done in an editorial setting.
Hippies. Alright maybe I should have said gorgeous hippies.
Holi Festival goers. This could be you! God that looks fun.
