Color variation is usually recorded
Color variation is usually recorded RRM0M
Color variation is usually recorded with cameras or scanners. Red, green, blue (RGB) color space is widely used in colorimetric measurement processes, but the combination of R, G, and B does not change uniformly with spectral wavelength and intensity. In 1931, the International Administrative Commission (CIE) defined the concept of three-dimensional values of X, Y, and Z based on the three-component theory of color vision. The human eye receptors are responsible for the three primary colors (red, green, and blue), and all colors are a mixture of them. XYZ 3D values are obtained using appropriate color matching functions. The laboratory model, which is indirectly derived from the CIE-XYZ color space, is made up of two color components a and b, and one lightness component (L). In this space, L* indicates lightness, and a* and b* indicate color directions: +a* is the red direction, -a* is the green direction, +b* is the yellow direction, and -b* is the blue direction. The center is achromatic; as the a* and b* values increase and the point moves out from the center, the saturation of the color increases. These two models represent a wider range of RGB. Ideally, they can reproduce an infinite number of color mixtures. [166]
