How much white

At what point would a "bay" become a "roan/bay roan"? Is it anything beyond rabicano roaning? I have realized that our mare has very consistent white hair distribution on her body and am beginning to wonder if perhaps that is part of the difficulty I am having in locating her registry information-searching the wrong color class.

A pic of the coat would really help but some people consider a horse with minimal roaning (a few white hairs) a "roan horse". It probably wouldn't hurt to expand your search to include bay roans as well.

Distance shot - shows how it is over her entire body (the light isn't that cooperative in showing the white)closer up - better shows how concentrated the white is

I have seen horses with less classified as roans. It couldn't hurt to add roan or .............what is it? Rabicano? To your search criteria.

I was actually going to make a post asking about this. Rocket has a fairly even spatter of white hairs all over his barrel and rump, but not as many on his shoulders and none on his neck. Could have been caused by something in his past, or is this a color thing? He is registered as a dark bay in the JC.

Genetically, I highly doubt she is roan. However, she COULD have been registered as one, since registries have a bad tendency to muck things up a lot.

If she was rabicano, being as solid as she is, she'd definitely have the white "skunk" tail at the very top.

As for roaning in general, it's a pretty consistant mix creating a whole new shade. The legs and head will always be a shade darker then the rest of the body.

My Arab mare has the same thing going on, scattered white hairs throughout her entire coat. Another good way to tell is that roan is like grey in that non-roan parents CANNOT produce a roan foal. One of her parents would have had to be roan for her to be roan.
