BLUE
The blue bengal is recessive at the density site. A normal "brown" bengal is really a black cat, but in the blue bengal the black color is diluted (not as dense). What makes the color dilute is that the color is not evenly distributed on the hair, rather the pigment granules are unevenly clumped. When this happens, more light passes through the hair and the color appears lighter. Even though the B site gene (brown or black) is not recessive, having a recessive at the "D" site (density) affects the appearance of the hair at the "B" site (black or brown).
What if the "D" site is recessive AND if the "B" site is also recessive? Then you'll get a lilac or a fawn depending on how recessive, but more about that later.
Since the density gene is separate then the silver gene and the snow gene and the marble gene, you can have a combination of both or even all three genes at the same time. Therefore it is possible to have a silver - blue marble bengal! Two cats with normal/standard phenotype (the way the cat looks) can carry recessively for blue. It takes both parents to carry for blue to have blue kittens. If two blue cats have kittens, all of the kittens will be blue.
Blue bengals are usually a soft grey blue color but there are other shades of blue varying from an almost white-grey color (this may be influenced by the snow gene). Paw pads, nose leather and tail tip are slate gray with pink overtones. The background color ranges from a peachy color to a pinkish peach color. Some blues will have some roufesing.
Blue bengals are not rare in that once you have known carries you can easily breed for blue offspring. They are not generally bred for in the bengal breed so you don?t see them as often as the recognized colors.
NOTE: I am look for a picture of a blue bengal so if you?d like to donate one please contact me.
CHOCOLATE:
A chocolate bengal would be recessive at the "B" site (the brown/black gene site) it is recessive to the "brown or black" and this gene control pigment shape. "B" is round, but the recessive of "B" is "b" which changes the round shape to an oval shape, which makes the cat appear chocolate brown in color.
Since chocolate is a recessive color (or a mutation) , it takes for both parents to either be chocolate or both to carry recessively for chocolate in order to have chocolate offspring. Since chocolate is a different gene then snow, silver and marble, you can have a cat who carries for OR is both or all four. Therefore, it is possible that you can have a cat that is a chocolate, silver, snow marble!
A chocolate cat has a pattern the appearance of milk chocolate, with a lighter background color. The tail tip, paw pads, and nose leather will also not be black but a chocolate color.
NOTE: I am looking for pictures of a chocolate bengal, if you would like to donate a picture please contact me.
CINNAMON
A cinnamon bengal would also be recessive at the "B" site except it is a further mutation of the "B" site then chocolate. Chocolate is dominant to Cinnamon and black is dominant to chocolate. Remember, "B" is round, but the recessive of "B" is "b" is oval and it is the recessive of "B" and cinnamon (b1) is rod-shaped and is the recessive to both "B" and "b".
Since cinnamon is a recessive color (or a mutation) , it takes for both parents to either be cinnamon or both to carry recessively for cinnamon in order to have cinnamon offspring. Since cinnamon is a different gene then snow, silver and marble, you can have a cat who carries for OR is both or all four. Therefore, it is possible that you can have a cat that is a cinnamon, silver, snow marble! But since it is at the same gene site as chocolate it is NOT possible to have a chocolate - cinnamon bengal.
A cinnamon cat has a pattern the appearance of what else? Cinnamon, of course! Cinnamon cats have a lighter background color. The tail tip, paw pads, and nose leather will also not be black but a cinnamon color.
NOTE: See pictures of a cinnamon bengal below
LILAC
Lilac gets more complicated because we have two gene sites at work to produce the appearance of Lilac, plus we have more then one mutation at each gene site that produces the lilac effect.
Lilac results from a mutation at the "B" (specifically "b") site and also at the "D" site. Remember, the "B" site is the "black" gene and the "D" site is the "Density gene. If a chocolate cat (recessive at the "B" site) is also recessive at the "D" site, the cat will appear to be a lilac color. Again, the tail tip, paw pads and nose leather will also be a lilac color.
FAWN
Fawn is the most complicated of them all. If a cat is the most recessive at the "B" site (specifically 'b1' / cinnamon) and ALSO most recessive at the "D" (or density site) , the cat appears to be a fawn color. Both lilac and fawn colors are extremely rare within the bengal breed but not within other certain breeds of cats.
NOTE: I am looking for photos of lilac and fawn cats, even if they are not bengals.
