Chevrolet is whipping up candy colors for its smallest cars, Sonic and Spark. Sonic will be offered in Deep Magenta Metallic, which looks like it might taste like grape gum. That's a risk, though the company has done it before. About one-third of our Sonic buyers say a cool paint job is an "extremely important" factor in their decision. Chevy is being just as creative when it comes to its smaller car, Spark. Out went Inferno Orange and in came Techno Pink.
