REINING IN ACCURACY FOR COLOR MANAGEMENT

A perusal of the World Book reveals color to be a remarkable physical phenomenon. Light is made up of multiple colors. When a light wave is refracted, or bent, it separates into distinct color wavelengths. Light-sensing cells in the human eye are each tuned to react to different wavelengths between 400 to 700 nanometers. That range allows us to perceive a realm of somewhere near 7 million different colors.
