Even fans of black-and-white film can’t deny that color brought new life to photography and motion pictures. And when it comes to learning what happens inside the body, there’s no substitute for color. Were it possible, for example, to map out real-time gene expression in our body’s cells using contrasting colors, scientists would gain a glimpse of vital biological processes that are currently invisible. The problem is that the glowing multicolor proteins used by scientists to illuminate the inner workings of cells are of little help in observing deep-seated processes in the body, because the thickness of tissues obscures the glow.
