Chromatitätsdiagramm

A chromatitätsdiagramm, also known as a chromaticity diagram, is a two-dimensional graph that plots the possible colors of light. It is based on the principle that any color of light can be represented as a mixture of three primary colors. The diagram displays the chromaticity coordinates, which are normalized values representing the relative amounts of each primary color needed to produce a given color.

The most common chromatitätsdiagramm is the CIE 1931 chromaticity diagram, developed by the International Commission on Illumination. This diagram uses the standard observer, a theoretical model of human color perception. Colors are plotted within a horseshoe-shaped region, with the spectral colors (pure wavelengths) forming the outer boundary. The white point, representing the color of white light, is typically located near the center.

Chromatitätsdiagramme are used in various fields, including colorimetry, lighting design, display technology, and photography. They help in defining, measuring, and comparing colors. For example, they can be used to determine if two colors are perceptually similar, to specify the color gamut of a display device, or to analyze the color rendering properties of a light source. Understanding a chromatitätsdiagramm is crucial for anyone working with color reproduction and perception.
