The Amber gene lights up the basic coat colour black especially in Norwegian Forest Cats. Kitten have a black phenotype at birth, then they lighten during their first year of life until they appear almost amber. Only the tip of the tail remains black throughout life. The mutation responsible for the Amber phenotype (e) is located at the extension-locus (E) which controls the generation of pheomelanin also in other species.
