Figure 1. Effect of Champagne gene action on base coat colors of horses (chestnut, bay, and black).

A) Chestnut – horse only produces red pigment. B) Chestnut diluted by Champagne = Gold Champagne. C) Bay – black pigment is limited to the points (e.g. mane, tail, and legs) allowing red pigment produced on the body to show. D) Bay diluted by Champagne = Amber Champagne. E) Black – red and black pigment produced, red masked by black. F) Black diluted by Champagne = Classic Champagne.
