Fawn. The name gives off a warm cute vibe and the wig really goes with that !!! Or you could do a spin off of fawn and call it "Fauna"

Lavender mist because it looks like a shroud of mist when it's poofy like that, and because it's a cold colour. Amethyst and Aquarius and the other one don't fit with a cold colour like that, they're more vibrant and warm. Mist fits this best
