Color Specialists Opinions needed

How do you get a Dun Paint with 3 stockings (he has a fist sized white spot on his belly and some freckles under his chin) and a sock from a chestnut overo mare and a palomino overo stud? The stud does have a dorsal stripe. I know there's no real explanation without getting them color tested, but I am just looking for opinions on how this happens. The purpose of this thread is because I am just curious and would like to further educate myself on color and genetics.

DISCLAIMER - Please nothing about breeding 2 frames together. I am fully aware of the lethal genes and the possibility of the colt having been a lethal baby. This is solely asking color opinions on how to frame overo's could produce a basically solid dun baby.

Pali stallion is probably a dunalino .. somebody carries dun. I've seen sooooooooooo many dunalinos called (and registered as) palominos.

One of them was dun, maybe it wasn't noticeable through the frame? I dunno, frame won't usually hide a dorsal stripe...? Somebody wasn't regestered as the 'correct' color. Dun is a dillute gene, and it's dominant, you can't get a grulla out of two solid black horses. One has to have dun for the offspring to get it.

Would pictures of the horses help?

Sure .. mom and dad if you have them.

Stud, you can kind of see the dorsal strip on one of these, the other you can see his darker colors really well



These two have mare and foal in them. The second he had started to shed and you can the color he was shedding off and you can see his dorsal stripe

Mom could have potentially dun too and mistaken for chestnut. I'd like some pics too.

Lol posted at the same time. Do you have any of moms back? In one she definitely looks chestnut but in the other age almost looks dun. Pic of foals back too?

I don't think dad has dun :/

Doesn't look like it .. but one of them does.
