The range of colors possible in a Bengal cat is enormous. From the nearly black melanistic to the nearly white snow leopard, Bengals come in great variety of color.

Above, right, a melanistic kitten. Nearly black, this cat does have a spotted pattern. Like the large black cats, the spots can only be seen up close. But, with this Bengal, you can get close without being eaten. At left, above, a pair of kittens showing great range of coat colors.
Black Brown
Brown/black is the most usual color for a Bengal, but this hardly narrows it down. The Brown/black Bengal can be anything from very light tan to almost completely black.
In fact, TICA calls it a "lackluster description" of coats that can be anything from cool gray to gold, bronze, copper, mahogony and with patterns from gold to black.
Snow
Some Bengals come in a much lighter range of colors. With an element of albinism from Burmese or Siamese ancestry, these blue and aqua eyed Bengals are called "Snow Bengals".
Melanistic
Melanistic, from melanism, indicates an increased dark pigmentation in coat colors. While melanism occurs in much of the animal kingdom, the most famous animals with melanistic coats are "black panthers", which is something of a generic term that covers black jaguars, black leopards and black mountain lions we see (rarely) in this part of the world.
Bengal Patterns
There are two types of Bengal patterns: Spotted and Marbled. These, too, come in great variety.

Spotted coats, like the two above, can come in nearly endless tones and shades of the accepted Bengal colors. The patterns typically get darker as cats mature.
Marble patterned coats, like the two below, show up as swirls - preferrably with a horizontal flow.
