Pinto and Paint are both color breeds, but two separate associations. The Paint only accepts horses with Quarter horse or Thoroughbred breeding. Pinto has 4 divisions, one for the quarter type called stock type, one for TB's called Hunt type, One for Arab or Morgan types called Pleasure types, and one for Saddlebreds called Saddle types. Many horses that are registered Paint, are also registered Pinto. There are two color patterns in both Paint and Pinto, and they are the same gene in both that cause the spots. Dubby is of the Tobiano color pattern, and Girl is of the Overo color pattern.
Porkpal, I have a TB stud too, and another Paint Stallion that is 15/16 TB. They are half brothers.
I will try to hunt up more pictures later, maybe scan a few.
