What colors do they come in and is there a difference between the colors?

Labradors come in three colors, black, yellow and chocolate. Black is black, yellow can range from fox red to creme and chocolate can range from light sedge to chocolate. A small amount (silver dollar size) of white is permissible on the chest. There should be no difference between the colors in temperament or type. It is likely more the difference between one breeders breeding program and anothers as to what they place emphasis on.
