Similar to the gene for the colour cream, the gene for champagne causes a lightening of the basic colour. The champagne gene is dominant and homozygous and heterozygous genotypes are almost indistinguishable phenotypically. The basic colours are modified as follows: Chestnut is diluted to Gold-Champagne, bay is diluted to Amber-Champagne and black is diluted to Classic-Champagne. Champagne coloured horses are born with unpigmented skin that develops black spots during the first days of life. In most cases the eyes are blue but darken as the horse gets older.
