Within Chows we have a few things regarding colours

DD= Not carrying dilute (Red, Cream or Black)

Dd= A solid colour carry dilute (Black, Cream, or Red)

dd= A dilute (Blue, Cream or Fawn)

KK= not carrying red (Black, Blue or Cream)

Kky= carrying red (Black, Blue or Cream)

kyky= Red (Cream, Fawn or Red)

EE= No cream present (Black, Blue, Fawn or Red)

Ee= Carrying Cream (Black, Blue, Fawn or Red)

ee= Cream

Every Chow will have these three things present, for instance-

A Black can be DD, KK, EE or Dd, Kky, Ee or any combination of those. I have found that a black carrying blue and not red tends to be a better colour of black for instance Dd, KK, Ee.

A Cream will any combination of the first two but always ee, this could be a reason for yellow vs white creams as an example.

A Fawn will be dd, kyky, EE or dd, kyky, Ee.

With this knowledge you can make a colour based pedigree.
