What is the blue-cream cat coat?

The blue-cream cat coat is a dilute version of the black-red cat coat which describes the tortoiseshell coat so the blue-cream coat is a dilute tortoiseshell. Blue is a dilute black. It is blue-grey. Grey cats are called ‘blue cats’ by the cat fancy as you probably know in recognition of the slight blue hue of the grey. It is between pale grey and slate grey. The purebred cat the British Blue is a British Shorthair with a grey coat.

According to the cat geneticist, Roy Robinson (Robinson’s Genetics) European and American ideals for this coat pattern and colour differ somewhat.

In Britain the colours 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.

Robinson’s Genetics

Variants include the following:

  • Blue-cream shaded
  • Blue-cream smoke
  • Blue-cream and white
  • Blue-cream point
  • Blue-cream lynx point
  • Parti-colour blue-cream and
  • Van blue-cream and white.

Gray colour, termed blue by the cat fancy is produced at the dilution or maltese gene locus by the allele d in the formular aaB-dd. The color is chemically black pigment (eumelanin) but with a dilution of the apparent color caused by the clumping of melanin granules in the hair shaft. This results in colorless areas of the hair shaft allowing more light to pass through the hair and thus lightening the color.

On the blue-cream dilute tortoiseshell coat:

The cream and blue-cream are dilute variations from the incorporation of d into the genotype: cream ddO, cream female ddOO and blue cream aaddOo. A pale rather rich cream is preferable for exhibition and these are the animals favored for breeding purposes.

Calico is tortoiseshell-and-white. There probably should be a substantial amount of white otherwise it is permissible to describe the cat as a tortoiseshell.
