Because our eyes, no matter how well trained, can be overwhelmed by the many variables that contribute to the color of an image, viewing standards have been well established. For the printing industry, standard viewing conditions for color evaluations and comparisons are a 5000√ Kelvin light source and a neutral gray surround.

Although we cannot measure how our brains interpret color, we can measure the physical properties that cause the sensation. The fact that color can be measured gives us the means to control color during the reproduction process and thus avoid the expense of trial and error.
