I'd list it as a GP, but I wouldn't think it horrible if I did see it used. It does have a really cool nighttime, cruising in a convertable, jiving music, neon lights (fuschsia ones, of course) sort of thing going on.
I think it would have to be a first name since it's so bright and loud. I don't think it would work as a middle name, and would come off as strange. But as a first name it would look bold and daring. So it would need something edgy to complement that. Of course edgy isn't my thing, so maybe someone else would be better at such combos. Stuff with Vs and Xs in it? Like Fuschia
Aviva, Fuschia
Xanthe, or maybe a Q name like Fuschia
Queenie. Hahaha, so not me, but I can totally see it.
Honestly, I thought of the color and didn't even think of the flower. I think most people will think that way. But I'd call Fuschia and
Dahlia's sister...
Zinnia.
