found this on wiki about it :D

Smoky black is produced by the action of a heterozygous (single copy) cream gene on an underlying black coat color. Therefore, smoky black is a member of the cream family of coat color dilutions, and found in horse populations that have other cream gene-based colors such as palomino, buckskin, perlino and cremello. All smoky blacks must have at least one parent with the cream gene, and a smoky black can be verified through DNA testing. Smoky black has been mistaken for faded black, dark bay or brown, grullo or even liver chestnut.

A smoky black horse usually appears to be a black horse and the dilution gene dilution factor is not visible. However, the coat may be somewhat more prone to fade to a brown shade if weathered or sun-bleached. Conversely, just because a black horse may fade in the sun does not necessarily prove or disprove that it is a smoky black.

Two copies of the cream gene on a black base coat produce a smoky cream, a cream-colored horse which is visually difficult to distinguish from a perlino or cremello, but can be identified through DNA testing. :)

I have a real life horse in my barn who is a smokey black and he is beautiful :x

I agree it's the Lp redshifting him. Cream seems to intensify the effect.
