You can register solid paint horses with AQHA. I have a mare that if I paid $1000.00 I could get her AQHA papers. Her sire is a QH and her dam is a paint. Same thing with my gray mare PT. The APHA was mostly started from cropouts of the AQHA. Leo was a great starter for the APHA. He had produced several cropouts to the APHA.
If a horse is QH x QH with enough color it can be considered an APHA registrable paint as well. They are called "Crop outs" in the APHA world. Paints are, Paint x Paint, Paint x QH, QH x QH with color, or Paint x TB. :) My parents bred paints for 20 years ;) Also, as someone else mentioned- Paints can be registered as Pintos because it's more of a color thing, but Pintos are rarely paints!
^^^ I could be wrong (as I don't own paints or QH), but I think the rule was changed recently, to where a Paint HAS to have a Paint registered parent now. I heard this was done now that AQHA did away with their white rule.
Pinto is a generic term to describe a MARKING not color
Paint is a bloodline
There is no such thing as a crop out. That has been proven over and over. There are minimally marked Tobianos that people mistake for a solid horse. So when that horse prodcues a pinto people think its a "crop out"
Most maximum overos are white with black dots in the ears. These are the horses that usually carry every pinto gene thus making them appear white. This also happens with maximum expression sabinos
My stallion lab tested to be Tobiano
My other stallion that is a lab tested visual frame over that also carries tobiano, splash and sabino
