Different colored horses?, What colors are there? Options

[Fennec]

I love horses and I heard that there are different colored horses in the game. How can you get different colored horses and what colors are there?

They come it brown with a dark mane and tail, brown with a light mane and tail, solid white, and solid black.
As to how you get the colors, it's random. But if you want a certain color you can save before you buy a horse and reload until you get the color you want.
