Color Fool

All right. I’m letting you have a say again. You have all day today (and perhaps throughout the weekend, if I’m feeling particularly game [!]) to guess what activity this guy is dressed for (other than success!):

Please do not disappoint me like you did in responding to last Friday’s fun free-for-all, where so many of you submitted the same answer, e.g. a variety of a fortune cookie. Clearly your imaginations did not run as amok as I would have liked. If they had, at least one of you would have guessed, correctly, that it was (and still is) an extreme close-up of Clara Barton.
Although you disappointed me on a grand scale, I still do appreciate your participation and wholeheartedly encourage it. Try to do better this time, though, all right?
