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
