Techopedia Explains Monochrome

Monochrome relies on two main colors – often black and white – as well as all the shades in between. The colors in a monochromatic monitor depend on the type of phosphorus used in the monitor’s display tube. In computer monitors, this color was mainly green, although a few monitors included red or white. Besides computers, the monochrome display was implemented in other devices as well such as cash counters, information kiosks and laboratory equipment displays.
