Here are some pics of my bengals, with color descriptions, etc.
This is Loki, a 1.7 year old male, brown rosetted (spotted) tabby. His background color is tawny/tan, brownish/red rosetttes with a black outline.
This is Jack, a 1 year old male, silver, black spotted tabby. His background color is silver with pitch black mostly solid spots. (Ocicats have solid spots, not rosettes)
This is Rodeo, a 1 year old male, seal mink spotted tabby. His background color is Ivory with mauve/brown rosettes/spots.
This is Kaehkili, a 2 year old male, brown spotted tabby. His background color is rufous with black spots.
This is Odin, a 1 year old male, brown rosetted (spotted) tabby. His background color is tawny/tan with paw print rosettes. The rosettes are brown/red with black outline.
This is Penny, a 1.5 year old female, tri-color marble tabby. Her background color is light golden tan, with black and mahogany/brown marbling.
This is Miss Spotty Paws, a 7 month old female, silver, black rosetted (spotted) tabby. Her background color is silver with black/gray rosettes and black spots.
There are more varieties that I don't have pictures for. As you can see, the bengal breed is indeed varied, in color combos, spot color and rosetting.
A lot of the early generation bengals resemble Ocicat spot patterns, but most bengal breeders are striving for rosetted cats so that's where the departure is for the most part.
There are lots of other subtle differences in body confirmation, head type and so forth that distinguish the breeds from each other, but the main thing most people see is the coat pattern.
I'm happy to elaborate as needed!
