The Siberian is recognised in 124 colours. Within this the Solid White has four different eye colours and each is recognised by a different breed number. Any amount of white is allowed, (i.e. white on paws, chest, belly, blaze, locket etc.) on all patterns and colours including the colour pointed variety. The colour pointed variety is sometimes refered to as Neva Masquerade. Allowance should be made for belly spots and shading on colour points.
The only colours that are excluded under all registering bodies are Chocolate, Cinnamon, Caramel and the corresponding dilute colours (Lilac, Fawn, and Apricot) in any pattern combinations (solid, bi-colour, tri-colour, tabby or colour pointed.). Non-permitted colours also extend to cats that show Burmese or Tonkinese colour restrictions.
The cross over of colour registrations between other registries and GCCF does not include "Golden Tabby" or any of the it's sub colour groups (e.g. Golden Tortie Tabby, Golden Shaded or Golden Tabby & White). These are not recognised under GCCF because the Golden Tabby is not a genetic colour, it is simply a colour expression of Brown Tabby. Golden Tabbies exhibit wide agouti banding on the hair follicles (limited black banding on the hair shaft) therefore allowing more light to penetrate through the coat giving it a warmer tone. All cats that are registered Under FIFE or TICA as a Golden Tabby will be registered as a Brown Tabby if transferred into GCCF.
