Russian Blue
Overall impression: Shall be a deep and even slate
blue colour without tinges, white hairs or spots.
Colour to be carried down the skin. Belly colour not
to be lighter than top colour.
Feet: Blue.
Eye colour: Black.
Genetics: (aarbrb). (I call this gene "rb".)
Known since: Known since: ?
Imported to Sweden from the US in 1998.
Not in standards in the NFRS, in standards in the US
as Russian Blue (RMCA, AFRMA).
When the colour Russian Blue was imported we already had a similar colour called German Blue (aadd, also called Blue/Graphite).
NOTE: German Blue and "Russian Blue" was
complementation testmated in July 1999.
Since they produced a whole litter of blacks
this proves that these genes are
situated on different loci.
When I saw my first Russian Blue I though it
was a badly colour bred German Blue, and therefore I
was pretty convinced the test mating between
Russian Blue and German Blue would produce
blue babies... But that was not the case!
