Through selective breeding, this effect has been maximised. In ticked tabby cats without silver, Wide Band restricts the pigment to the end of the hair leaving a pale golden band between the skin and the pigment. Although 'Wb' is treated as a single gene for simplicity, it appears to act as polygenes with an additive effect. Wide Band is independent from the Inhibitor gene in golden cats, the dominant Inhibitor is absent, but wide band is present. There is a misconception that when a cat with a silver parent isn't silver, it must be golden by default. In Persians, Exotics and British Shorthairs, golden seems to result from with the wide band gene(s) and many of the cats have silver (dominant Inhibitor gene) somewhere in their ancestry because the wide band effect was selectively increased when breeding for very pale chinchillas. This meant that Siberian cats registered as 'golden' by FIFE or TICA are re-registered as brown tabby (etc) when transferred into GCCF. Siberian 'Golden Tabby (with or without white),' 'Golden Tortie Tabby (with or without white),' 'Golden Shaded' etc are not viewed as a genetic colour, but as a colour expression of Brown Tabby due to wide agouti banding on the hair shafts which limits the black banding and gives a warmer, brighter tone.

This is not recognised as 'golden' by Britain's GCCF (a very conservative cat fancy). Some registries recognise the 'golden series' in Siberians. The colours not recognised are chocolate/lilac, cinnamon/fawn, caramel/apricot in any pattern. The Siberian is recognised in most colours and patterns, including colourpoints (Neva Masquerade), but not mink or Burmese colour restriction. Note: Corin is also known as â€œVariable widebandâ€ and uses the symbols VWB+ (wild type), vwbSIB, vwbeSIB, vwbBSH. In earlier versions of this article, 'extreme sunshine' (wbESIB) was called 'copper' (cuSIB). For more pictures and explanations please look at and select Sunshine_Colour_EN_Webinar. 'Bi-metallic' was a nickname for cats showing both silver and golden in their coat i.e. Pallavicino and was proposed for the first time by M. The name 'sunshine' comes from the joint work of E. Note on Terminology: 'Sunshine' is the genetic name for the golden colour in Siberian Cats.
