Disagree with the concept. I would recommend studying pixel art for examples of really strong color usage - most modern styles work within an economical palette, just like in graphic design. Black is commonplace, it's how it's used that matters. The scene as a whole has similar considerations for contrast and weight as graphic design, even though the individual elements tend to emphasize detail and lighting.
