Xyz Color Space

The xyz coordinates for the reddest possible red greenest possible green and bluest possible blue are called the color space s red green and blue primaries.

Xyz color space. Colored area in above chromaticity diagram is the cie xyz 1931 color space. This area is the mathematical limit of human eye with respect to color. This area is the mathematical limit of human vision as far as color is concerned.

The xyz coordinates for the lightest light is called the color space s white point. Because three dimensional objects can t be illustrated very well a two dimensional representation had to be found. It utilizes three main concepts it is based on and derived from the cie rgb model which was formed from actual experiments.

With x 1 y z 0 are imaginary colors i e they cannot be physically realized. Cie xyz color space. Wavelength values in nanometers are indicated in figure 3.

The primary colors of cie xyz color space e g. In order to eliminate this drawback a linear transformation over the rbg space is made leading to the tristimulus values andwhich take only positive values. Cie 1931 xyz was the first attempt to produce a color space based on measurements of human color perception and the basis for almost all other color spaces.

All this put together produced the well known cie xyz color space which is also known as cie 1931 color space. One of the first mathematically determined color spaces is the cie xyz 1931 color space created by cie international commission on illumination in 1931. The cie xyz color space encompasses all color sensations that are visible to a person with average eyesight.

This color space is based on the results of the cie rgb version of the human eye. Colors for monochromatic light are located on the spectral locus of the chromaticity diagram which is the curved boundary of the shown gamut. In 1931 based on the results of the cie rgb version of the human eye cie mathematically determined a color space the bull pen a theoretical area called the cie xyz 1931 color space.
