The color gamut describes a range of color within the spectrum of colors that are identifiable by the human eye (visible color spectrum). The technology for modern day products to reproduce colors varies from device to device, with digital cameras, scanners, monitors, printers, tablets, projectors etc. all reproducing a different range of color. In order to standardize this color difference, various methods of measuring color range have been used to create communicable ranges of color so the capabilities of each device are understood. In 1931 the CIE (International Commission on Illumination) established a standard observer, with the commission recommending the use of chromatic coordinates xyz (CIEXYZ).
