Man, this was a hard one. I love Brights Brightly because he's a unicorn, and a yellow one to boot. But I also love Midnight Dreams' dark, mysterious color scheme.
In the end I had to go for Midnight Dreams for a few reasons. First, her name rocks. Brights Brightly . . . bleh. Midnight Dream FTW. Second, Brights Brightly has glitter slathered over his horn and symbol. Words cannot express how much I loathe that glitter. Especially since I just spent a half hour in a ventilator mask, in the rain, scrubbing it off of a unicorn I wanted to customize while trying not to breathe in the noxious fumes.
STUPID GLITTER I HATE YOU!!!
