CIE color model

What is CIE color model?
The CIE color model is a color space model created by the International Commission on Illumination (Commission Internationale de l'Elcairage, CIE). It is also known as the CIE XYZ color space or CIE 1931 XYZ color space.

The CIE color model is a mapping system that uses tristimulus values (a combination of 3 color values that are close to red / green / blue) drawn on 3D space. When these values are combined, they can reproduce any color that a human eye can perceive. The CIE specification aims to be able to accurately represent every single color that the human eye can perceive.

The CIE color space was created back in 1931 to map all colors perceptible to the human eye. It was made independent of any technology that could represent colors, which is why it is considered the most accurate color model. The CIE color model is a three-dimensional model that takes into account the chromatic response of the eye. a response that changes when the cones across the retina differ in their response to light and color in different areas of the retina.

The CIE color space was the result of a series of experiments carried out by John Guild and W. David Wright in the 1920s that led to the development of a model that was completely independent of any means of reproduction close to how humans perceive color. As a result, the CIE color model is unsuitable for use with many technologies, including monitors and printers, although it is widely considered to be the most accurate color model.
