My favorite alt pony is Violet from the birthflower mail order ponies. I have a special fondness for the mail order ponies because my mom used to order them for me when I was a little girl. I have (and adore!) the original Violet but I love the colors of alt version too. This photo is from my little wiki as I do not own the alt version of Violet. Thanks for hosting this contest!
I’m from Sweden and I have several favourite alternative Ponies, but my current one is the one I received today and that has been my grail for many years, Italy Magenta Blossom. I love her color combination. My friend/rival found on at a flee market when I was a kid and I’ve been wanting one since then. And today I finally did (not my photo).
