![]() ![]() The effect of amber will depend on the base color: black amber cats generally have a hot red color, while blue amber (also called light amber) often have a more peach/cream color. The previous articles in the series cover:Īmber is a coat effect that transforms black hair into yellow hair, which gives amber cats generally a warm golden color. Note: Before reading this article, I recommend you to read the articles of the first series on basic cat coat colors: some of the genetic explanations will be useful to understand this article. As we will see in the article, amber is specific to Norwegian Forest cats and I will explain what are its properties, its history, and the genetics that make it happen. I will start with not just any color, but the one of my cats Néline and Praline: the amber color. It is now time to cover the breed-specific colors. Your question is of sufficient depth that a decent explanation would need come from a geneticist who's been involved specifically with the study of these particular loci, and their interaction, which narrows the field considerably.In a previous series of articles, I presented all the basic cat coat colors. The particular interaction between the modifier alleles and the Melanin Inhibitor, Agouti and Banding mutations falls at the extreme outside edge of our understanding at present (my own knowledge stops roughly at the spelling of the word "cat"). Les Lyons is in the midst of a long term study of Silvers (and Goldens) which will ultimately answer the whole question ( doubtless - she's absolutely tenacious), and the research call may be found here: Silver and Golden Chinchilla Persians, which show the effects of WB and silver). ![]() ![]() Simple Truth: we don't yet know enough about the interaction of Wide Band and Polys to even comprehend how the complex values render themselves, though we know the extremes of Wide Banding, since breeders have been "accidentally" using this as a focus in certain cats (e.g. a badly expressed or weak "a" or an overexpressive "I" will perform almost as the Dilution allele does, yielding a washed-out Smoke or Cameo). The expressive value of the modifier or modifiers (predicted) gives various Smoke and Cameo coats (e.g. Paw pads: black.Įye color: green, hazel, or brilliant copper.Īll Tabbies are either AA or Aa, and the Inhibitor allele - I/i - produces hairs which are either white at the base (the dominant: I), or (with the recessive: i) self-coloured at the base. Lips and chin the same shade as the rings around the eyes. Silver Tabby (classic or mackeral) Ground color pale clear silver. Yellow, gold, amber, or any color other than green or blue-green. Nose leather:brick red.Paw pads: black.Eye color:green or blue-green.įor incorrect eye color, incorrect eye color being copper, Rims of eyes, lips, and nose outlined with black. The general effect to be much darker than a chin-Ĭhilla. On the chin, chest, stomach, and under the tail. Sides, face, and tail from dark on the ridge to white Shaded silver: Undercoat white with a mantle of black tipping shading down from Here is the quote from the CFA breed standard on both: The bottom photo is the kitten on the left at about 16 weeks. In the photo below the litter of kittens is less than 24 hours old. Generally, my silver kittens tabby markings faded within a couple of weeks from birth, whereas the goldens take longer. Most silvers (and goldens) are born with some tabby markings, but they fade. While it isn't a great photo I hope you can see the mantle of tipping on his back. ![]()
