Interesting twist. So if I understood right, since I'm still slightly brain dead when it comes to agouti for some reason, you're starting to wonder if sooty on a bay is different than sooty on say a chestnut?

Any thoughts on what would cause the sooty on a chestnut even though they lack the black pigment? If I recall they don't yet have tests for sooty right?

I still think sooty is there, but only on red horses. It presents differently on red horses, not the "top down" that is associated with sooty on black based horses (which, like I said, I am not convinced is sooty and think instead it is associated with agouti). When sooty is on red based horses, you get dappling, you get grey in manes and tails, you get all over darkening. I haven't seen many examples that show the classic "soot dumped on top of the horse" look.

Mods, grant me the serenity to see the opinions I cannot change, courage to change the ones that should change, and the wisdom to spot the trolls.
