Chromatizitätsdiagramms

The Chromatizitätsdiagramm, also known as the chromaticity diagram, is a two-dimensional graph that represents the chromaticity of colors. Chromaticity is a property of a color that defines its hue and saturation, independent of its luminance or brightness. This diagram is a fundamental tool in color science and is widely used in fields such as photography, printing, and display technology.

The most common form of the chromaticity diagram is the CIE 1931 chromaticity diagram, developed by the International Commission on Illumination. This diagram is shaped like a horseshoe and plots the x and y chromaticity coordinates of visible colors. The outer boundary of the horseshoe represents the spectral colors, where the longest wavelength (red) is on the left and the shortest wavelength (violet) is on the right. Moving inward from the boundary towards the center represents a decrease in saturation, with pure white light located at the center.

Colors that fall on the same straight line within the diagram can be mixed to produce white light. The diagram helps visualize the gamut of colors that can be reproduced by a specific device or system. By comparing the chromaticity diagram of a display with the diagram of a set of colors, one can determine if the display is capable of accurately reproducing those colors. It serves as a universal reference for color specification and communication.
