Please do not keep asking the same question: ask for clarification in the existing questions and wait for a response.

If you have an image...read it using imread. If it is colored image, it will be 3D matrix, you can extract R,G and B colors from this.

I = imread('your image') ;
R = I(:,:,1) ;
G = I(:,:,2) ;
B = I(:,:,3) ;

Ardit Oseku just adked the identical question. Are you working together? The solution can be found in my answer there: https://www.mathworks.com/matlabcentral/answers/361216-how-can-i-obtain-the-brightness-value-of-the-image-taken-by-any-camera#comment_492790 Basically you need to do color standardization with an X-rite Color Checker Chart. I give all the math formulas you need in my attachment there. I do this color calibration and standardization all the time in my job.
