Roans often have different degrees of roaning between the seasons. It can also vary from year to year (one year they'll have a lot of roan, the next year maybe not so much).
The difference between the brown and bay is sometimes subtle because they are caused by variations of the same gene, Agouti.
One of the things that makes a horse brown instead of bay is the sometimes drastic color changes between seasons (dark where they are almost black, to bay, to a lighter tan similar to a buckskin, etc) and the noticeably lighter "soft" areas on the horse.
If you look at your guy, his muzzle, his flanks, behind his elbows, down on his chest, much of his belly, and just below the point of his butt are all lighter than the rest of his body. That's almost always a tell-tale sign that a horse is brown and not bay.
Bay horses can and often do have pangare - the soft-white points on the muzzle, elbow and flanks. Brown horses will always have some degree, though on a few, it's very difficult to tell. Pangare is not what makes the horse brown or bay, but it may indeed be linked to the At (brown agouti) variation. The research does not go that far yet.
