profile

In 1931,the CIE(Commission Internationale De L'E'clalrage)setup a series of visible spectrum color space standards.The Basic CIE color space standardS iS CIE_XYZ.lt iS built on standard visual observerson the basis of ability to see,and it reflects the standardS scope of color by eye.Based On CIE_XYZ there are CIE_XvY,CIE_Lab,CIE Lch standard color space,etc.

At present,the CIE Lab color space iS the most commonly used in the industry.In ClE Lab color space,L value stands for color brightness and a value stands for the Green-0n-red value.and b value stands for the blueonyellow color value.If determine a value of color by only a group Lab,it will be not practical.However,we can determine the differences among them by comparing two groups of Lab values.
