What is CIE?
The CIE color difference formula was introduced to evaluate precisely the color differences that are observed when studied by the colorimeters and directed by the human eye. These differences are usually found due to the size of the product, shape, illumination and threshold of the human eye. These color formulae are not introduced only to build a color space but are proposed to examine the exact color also. CIE has added many color spaces such as CIE L*a*b*, CIE L*a*b*c*h*, etc. The formula is used to calculate the difference of lightness with L*, difference in the saturation through C*, the difference in the hue angle with h*by making use of various color coefficients.
What does all the CIE color space determine?
Consequently, the actual determination of color using the color space CIE L*a*b* color system, it helps the user to determine the saturation dependency, lightness dependency, and hue dependency. With the mentioned color space, color difference formula, the color difference assessment is signified by color difference ΔE*ab and index of chromaticity difference ΔE a*b* were a perfect square or a circle in the L*a*b* solid color space. With the CIE color space, the effect on the hue angle is also considered. The formulas of color space cope up with the characteristics of color discrimination such as a change in the direction, or deviation from the direction of saturation.
