CIE color space coordinate chart:
COLOR DIFFERENCE FORMULA
     Eab= [(ΔL*)2 + (Δa*)2+(Δb*) 2]1/2
     L= Lsample Lstandard (lightness difference)
     a= asample astandard (red /green difference)
     b= bsample bstandard (yellow / blue difference)
Working theory:
Compare the color difference between sample and the measured subject .Then output CIE_Lab 3 groups data,and the 4 groups of E, L, a, b data after comparision.
 
     E stands for the total color difference
     L + stands for partial white, L stands for partial black (comparing with prototype)
     a + stands for partial red, a stands for partial green (comparing with prototype)
     b + stands for partial yellow, b stands for partial blue (comparing with prototype)
