Pearl
Pearl is a marking that creates a bright sheen on the coat, similar to champagne. It can appear on any base coat and lays beneath most markings. It can have a gradient and should be subtle against the coat. It can appear with tarnish, causing a countershading effect, or layer on champagne to cause a brighter shine. (Horse should not appear over-exposed or extremely bright).
Heterozygous Pearl will cause a subtle shine on any base coat, without any dilution effect, except in the case of cream. If heterozygous pearl is combined with heterozygous cream, the coat will have a double cream effect with shine. Horses with pearl + cream will have blue eyes.
Homozygous Pearl will cause a champagne-like dilution to the coat. Double pearl is slightly more muted than champagne in color. Double pearl horses will have hazel eyes.
