We all can sit here and guess all day but a color test will tell the story.
Keep in mind different monitors will show colors differently. On MY monitor she looks like a bay. But I would never say for sure from a computer picture
There are many, many horses that are bay and black without being brown. This doesn't look like one of them to me. This mare is a classic bad-ass brown - dark in the winter, probably with the classic "mealy" on her nose and flank, shedding out to a bay colour in the summer. The paleness is still visible on her flank, while not glaring. In this case, I am not just going by the horse I see in pictures, but by the description of the horse across different seasons. As I am sure you already know, the best way to tell a horse's colour without testing is to see how it changes, either as the horse grows from foal to adult, or as the seasons change.
