Cat color
Blue
In coats and feathers the fanciers' blue: a dilution of black that looks slate grey, as in blue dogs, Russian Blue cats, blue rabbits and blue pigeons. In eyes and eggshells a true blue.
238 Cat breeds list Blue. It is in a club standard for 209 breeds. At least one club disqualifies it in 8 breeds.
