Most of the image was colored in the different brown shades. The main body was E11, 13, 15, 17 and 18. His mane was the E50, 51, 53 series. His hooves I went over with Warm Greys to add a bit of the browner colors since they were stamped in the black. The post was colored with the E70, 71, 74, 77 series. The flower is YR21, 23 and R24 added in the middle of hte petals and then blended. the greens were YG21, 23, 25, and his eyes are B21, 24. I don't think you can see it here very well, but his teeth are outlined (uh inlined???) in Y0000 - cuz really a horse with white teeth just didn't seem right LOL.
I have a close up of the Horse and more information about the distressing on my blog if you are interested.
