Champagne is a rare dilution gene with some interesting properties. It can turn a red horse golden similar to the cream gene, however it affects both red and black pigment equally. It also dilutes the skin of the horse to a freckled pink, which can cause a unique purplish appearance in dark horses.
Champagne horses are also unique in that they have hazel eyes. A champagne foal is usually born with blue eyes which then gradually darken to green, amber, or some shade of hazel in between the two.
