The color gamut is another name for the color reproduction range or color spectrum about display technology. It provides measurable data on the spectrum of real colors that a screen can replicate. It so shows the spectrum of colors that may be shown on a display.
Generally speaking, color standards like sRGB, Adobe RGB, and DCI-P3 that are shown on the CIE chromaticity diagram are used to express the color gamut as a percentage.
A metric called color gamut, also known as color space or color representation rage, is used to measure how closely a color may be represented on a display.
A range of colors that may be shown on a display in percentage terms is called color gamut, and it is mapped using color spaces found in CIE standard colorimetric systems like NTSC, sRGB, and DCI-P3.
A display can represent a wide range of colors within the standard color gamut if, for instance, it meets DCI-P3 100% coverage, which indicates that the display covers the DCI-P3 color gamut 100% or more.
