Like a black T-shirt with a splash of color, the Cobalt/Black version of the portable Nintendo DS grabs your attention. It looks good whether it’s toted in your school backpack, pulled from your purse or riding with you on a family trip. Cobalt/Black marks the seventh color in the Nintendo DS Lite palette. It joins Polar White, Coral Pink, Onyx, Crimson/Black and the limited-edition Gold and Metallic Rose.
