Back in the day,, Paint,Pinto Appaloosa same with the buckskin and Palomino, were all color breeds, if the horse did NOT display the colored coat patterns they were not registered with that breed. Not all Paints were from AQHA. GO look at some of the horses in AQHA, there were Colored horses, names like Old Joe and Ole App and a few others. THEN the rules changed and a breed type was made, no color, and most were bull dog type horses and short, Then they allowed TB and allowed a horses to be Appendix bred. If you LOOK at any breed how they started and what they are NOW , the horses look totally different.
