The black (brown) spotted tabby is the most common Bengal color and pattern. This colors is abbreviated as BST.
They also come in marbled, abbreviated as BMT.
Brown Bengals can be any shade of brown from red-brown to light sandy brown to golden to tawny and everything in between! All of these shades are accepted under the standard. Rufoused is a term that refers to Bengals with more of the red/orange color to their fur. A Bengal that does not have the red tones is said to be a "cool brown."
Brown is represented as A/A on the genetic color panel and is called "full color."
The TICA Bengal standard says "eye color is independent of coat color except in the lynx points." This means that Bengals can have any color eyes without being penalized in show, except lynx points which MUST have blue eyes.
