Dilute/Blue
The gene d has had recent discoveries and has now been renamed d1. This mutation alone does not account for all dilute color phenotypes. A second and third dilution MLPH variant d2 and d3 has been identified. Still, two copies of any of the three dilution variants, or any combination of two of these, are necessary to lighten the color.
