Question on black thoroughbreds

Interesting discussion.

One of the stallions in the Leg-up auction is Sagar who is a double dilute. There are several foal photos, and quite a few are foals who look very close to black to me. I suppose this is “sooty black”, and could well explain why a dilute gene really could have been hidden in the TB genetic pool for eons.

I’ve raised a couple that we’re most likely black, no brown anywhere, even the muzzle and flanks. However to avoid the extra headache I registered them as dark bay/brown.

A true black horse has a ‘blue’ sheen to it. Might not be noticeable at first, but put the horse beside a dark bay, and you will certainly see it.

I’m not sure I understand - if you are saying Sagar is the sire of those “very close to black” foals, then they are smoky black (not sooty black) - black with a single cream. And yes, they are very, very often mistaken for black, as it’s not common for them to look anything otherwise. Some do (look up Nightlight by Guaranteed Gold) but most don’t.

And yes, that can make cream hide for generations if foals end up being smoky black as well.

There have even been some buckskins who are so dark they never are suspected to be as much - look very much like regular brown or bay.
