I liked the colors used for Pinkie's Rainbow Power form, and the design was kinda nice. But I still decided to re-do aspects of it to better match my version of Twilight's rainbow power form So I changed the leg colors, and added a bunch of markings. My idea was something like, the back markings to represent wings, and the forehead markings to represent a horn; implying that they're closer to alicorns I guess? Sort of, they're all combining into one force, so the earth ponies get aspects of the unicorns and pegasi, and so on. I dunno, I think it looks nice at least
