Thank you all.
The Marchadors are more "lean" built like an Arab but not as lean as them. They can have some stockiness to them similar to a QH but nowhere near as thick. Diego is a little on the chunky side due to lush green pastures.
When I was breeding, I didn't breed for color at all, to me color was a bonus. Yes there have been some horses I did buy because I liked their color, but not just because of their color, they also had to have good conformation and a nice pedigree. I have never bought or bred a horse just because of their color. I do, however, like having a rainbow in my pasture. lol
