Exactly correct. I have a sooty bay pinto mare who's dam was sooty buckskin and looked seal brown. Her filly, my two year old now, has a smokey grullo sire (dun on black with cream). Genetically she is a sooty buckskin tobiano, looking at her she looks like a dunskin. Sooty creates a face mask, dapples, and many times but not always a dorsal stripe. In most cases the dorsal stripe can be distinguished from a dun dorsal stripe. In my filly's case it looks like a dun dorsal stripe, and the only way to tell just by looking at her that she did not inherit dun is the dark face mask. Like many buckskin mini's when she is clipped she looks dark grey, and only in the last year has she started to grow in the deep gold. Her dam, my bay mare is the same way, very dark when clipped, dappled, no face mask, but her dorsal has lines or stripes generating out from it around her withers.Nine times out of ten if you here someone call a horse a chocolate palomino it is a silver dilute. Sooty palominos really don't look chocolate as Mona pointed out and "chocolate" is simply a descriptive term. Anything chocolate shaded with a light mane and tail can and has been called a chocolate palomino by someone at some point. I've seen this flowery descriptive term used on silver bays, brown silvers, silver blacks, silver smoky blacks, brown silver buckskins, silver buckskins, silver duns, brown silver duns, flaxen liver chestnuts, and only very, very rarely on sooty palominos.
Not sure what site you found that on Jenny but most people use the term sooty as opposed to smutty. Smutty is usually used to describe a color that has sooty patches but is not all over sooty - aka has "smut marks". That's the first I've ever read of anyone thinking the darker shades are homozygous for sooty. The fact of the matter is no one knows how sooty is inherited.
He's very nice and looks like a nice silver black to me.Okay - since there is a variation I have attached a picture of him. Looking at him what would you say the color is?
thanks.
