A blue cream colored cat is a dilute tortoiseshell cat (dilute tortie). The blue-cream colour is the dilute form of the tortoiseshell pattern. The blue replaces the black and the cream replaces the red color. The recessive dilute gene (dd) softens the colors.
The book, Robinson’s genetics, says that this coat pattern differs slightly between America and Britain.
“In Britain, the colors of the blue-cream should be softly intermingled whereas in the USA preference is given to those cats with segregated patches of blue and cream.”
