Take a look at this. Horse #1 w/o color. You can see he is front end heavy, back at the knee and weak through the coupling. Color makes him look a lot better than he is.
A horse with color and conformation is going to cost a few bucks. The nicest one I can recall (and I tried to breed a mare to him) was Sacred Indian. What a nice conformation (like a good Thoroughbred). See if you can find photos of him. He could have done eventing etc.
Another one that was very nice was the warmblood Art Deco. Horses like this, that were colorful and put together well, are very costly.
Keep searching and expect the search may take a LOOOONG time.
