Color Management Part 1

The fundamentals

Color management starts with the light source. Any color we can see is contained in the light by which we are viewing an object, i.e. the sun, a table lamp, etc. As a form of energy, this light travels through space in wavelengths. The wavelengths we're concerned about are in the visible spectrum—wavelengths that are between about 400 nanometers (blue) and 700 nanometers (red) long. Below 400 nm would be ultraviolet, and above 700 nm would be infrared.
