White: pink-eyedcc (albino; covers up the actual color/marking so can be either an agouti-based or black-based color) or cece pp or cec pp or chch pp or chc pp. Note: extremely diluted P.E. Self colors or a P.E. Marked with all markings bred off can look like a P.E. White

Note: Capital letter=dominant genes unless otherwise noted; lower case letter=recessive genes

“–” means that either the dominant or recessive allele could occupy that space without affecting the outcome

Note: Lilac U.S. = Dove U.K. (P.E. Black), Dove U.S. = Lilac U.K. (Chocolate Blue or Dilute Chocolate)
