I love eggplant. I can't think of any horse that doesn't suit eggplant - it's just a hard colour to find. I'm planning to just buy some stuff and dye it myself.
My buckskin mare is in eggplant and sage green. It looks amazing on her golden summer coat with her black legs, mane, and tail. It is hard to find!
For my grulla filly, I have her in turquoise and pink!
I love having a double color pattern because you can mix and match halter, polo wraps, boots, whatever!
