This is actually what brought up the question. Cinny's dam is a solid sorrel with no white markings at all. Her owner has been breeding her to paints swearing that she will one day throw a paint. 10 foals later, no color. Cinny is the first in a long line of solid paints from this mare.
I don't know if she has ever genetically tested the mare as I'm not close enough to the person to ask, we are mere acquaintances, mainly because I 1) bought a horse from her and 2) we participate in a lot of the same clinics. I've seen all the offspring in person back when I got Cin, and the ones who have been born since, on her Facebook... and she always seems disappointed when the foal is born....solid. Some of the more recent studs were guaranteed color producers too.
