I'm personally not a fan of it. I like that it's gender neutral but it's one of those names that I just can't picture on an adult. I don't think it ages well. Some combos that I think may work:IndigoChristine IndigoSuzanne IndigoMelisande IndigoAlicia
I suppose it could be a girl's name. I know a little boy, age 2, named Indigo. Strangers(not his family, though)tend to call him Indy, but he doesn't like that, he points proudly at himself, and says "Indigo!"sorry no combo for the moment, I'm not good at that.
