SOOTY
Description:
The SOOTY/SMUTTY factor is generally believed to be responsible for most the liver chestnut, chocolate palomino, sooty buckskin, sooty dun, mahogany bay, and brown
colored horses. Sometimes counter-shading pattern can appear to be a form of striping, but
not including leg barring unless the Dun factor is involved as well. Some foals are born with what appears to be a dorsal stripe, which will spread out over the back and sides as the foal matures. Foals born bay with a counter-shading stripe will generally turn mahogany bay. Foals born charcoal gray with a counter-shading stripe will mature black. They are usually mistaken for Grullo's which are born yellow to light gray, and turn mouse gray as they mature. Foals born chestnut with a counter-shading stripe will usually become a darker or liver chestnut. This factor is not at this time recognized by N.Q.H.R. as a separate color, but as an additive factor on several base colors.
