With the TBs, I can't remember if it officially passed or not, but it was up for vote to have the TBs registered with the APHA put into their own subregistry like the way solids are separated. Basically distinguishing them as yes, they are colored, but not completely American Paint Horses.
Oh the debates of common term colors vs. genetic colors. Based on those pictures, I would have called your kid a bay, but I could see where a Cr gene could be there too; no one can definitely tell anything without color testing. UCD testing isn't really very expensive. On a rescue gelding, it may not matter much, but anything anyone plans on breeding that would have an increased value depending on color, I don't see why more breeders don't color test.
