My Simself is my avatar. I don't have blue hair (might not go over well at work), but if I could, I'd totally have multicolor hair. I asked my simself for a picture to post and she decided on this one:

That's her and her daughter (based on my daughter, who had pink hair at the time). I have a Simblr with a few little adventures my simself and daughter went on together, but it hasn't been updated in a while. Real life gets in the way sometimes, am I right?
