...I feel like I'm watching Sleeping Beauty again. Anyway, Blue!

Depends on the personality, I think; blue if you're aiming for "cool" or reserved, and purple if you want her to seem more outgoing. Purple also contrasts with green starkly, too, so it'd be a good color if she's a rival with Julie, but blue would fit a gentler relationship.

Blue. It's a "cool" color, and gravity isn't traditionally a "warm" superpower.

Blue. Unless Principia and Julie both do the hair-dying thing, but Principia does it better...

Why not both? Have some cool hair dye excuse.

I say pinkish, just to contrast with Julie, but they both look decent really. Also, happy new years!

Pinkish. And have a happy new year! (and get some sleep). AN doh , shit it is 5:30 AM and I should be asleep too.
