CIEsystemet

CIEsystemet is a system for describing colors, developed by the Commission Internationale de l'Eclairage (CIE). The system was first published in the 1930s and has undergone several revisions since then. The main goal of CIEsystemet is to provide a method for quantifying and categorizing colors in a consistent and universal way.

At the heart of CIEsystemet are the color matching functions, which are used to describe how colors are perceived by the human eye. These functions take into account the way in which the retina responds to different wavelengths of light. Based on these functions, CIE system uses a system of color spaces, which are three-dimensional arrays of colors.

The most widely used color space within CIEsystemet is the XYZ color space, also known as the CIE 1931 color space. This color space is used to define the color coordinates of a given color in a three-dimensional space. The XYZ color space is defined by the x and y coordinates, which are used to specify the color, and the Z coordinate, which is used to specify the luminance.

CIE system has several other color spaces, such as Lab and Luv, which are used in various applications, including colorimetry and color science. These color spaces are used to describe colors in a more detailed and accurate way than the XYZ color space.

CIE systemet has become an international standard for color description, widely used in many fields, including color science, photography, printing, and computer graphics. The system provides a fundamental framework for understanding and working with colors.

The CIE system has undergone several revisions over the years, with new color spaces and technical specifications being added.
