Chestnut, Wild Gray and Chocolate Agouti



Chestnut agouti has the color genetic codes of A-B-C-D-E-  
Within the same genetics, a modifier could make the color a lot darker than the "regular" Chestnut, such darker version is called Wild Gray in the old SOP.

The name of the modifier is believe to be called "Umbros (Darkening) modifier". (We thank Candy for finding this information).
