-- What It Is: After decades of obscurity, brown leather car interiors are making a comeback. A growing number of auto makers are offering coffee- or chocolate-colored hides in high-end models as well as some lower-cost vehicles. Amid the popularity of brown-leather interiors, some makers are using the color for exteriors as well. Buick is using brown as its "lead color" for the launch of its new Enclave luxury vehicle

Consumers used to think of brown as earthy and dull, but now they associate it with luxury goods and indulgences from expensive coffee to leather furniture and oversize handbags.

-- Cost: It is part of a $1,250 trim upgrade Mazda 5 minivan. BMW charges $1,450 to upgrade to leather from vinyl on its 3-Series cars but brown doesn't cost any more than other colors. There's no extra charge for Espresso leather on the Mercedes-Benz CL550 luxury coupe, which costs about $100,000
-- Comment: The emergence of brown is part of a wider trend toward more colorful cars. While parking lots today seem to be a sea of mostly black, white and shades of silver and gray, color forecasters say they expect to see more blue, purple and orange cars in coming years.
