Normalization of figure based on colour (RGB)

Hello,
I have my code here;
color_image = {};
map = hsv(256);
for i = 1:size(Data_SWS_BMd_A3,2)
image = Data_SWS_BMd_A3{i}.SWS_Img;
uint_image = uint8(255*mat2gray(image));
color_image{i} = ind2rgb(uint_image, map);
end
I want to normalize my figures base on one range colour to find a relationship between them.
Can anyone help me 1) how I can nomalize it?
2) how should I change the binary of my picture to expand the range of colour?
I need the answer soon, I would be grateful if anyone can help me regarding that.
Regards
Thanks

I can't really tell you how to standardize the images unless I know what's in it, and your intent. I mean you could simply use rescale(rgbImage, 0, 255) but that may not be what you want. Maybe you have a Color Checker Chart in the image and want to use that do to a true color standardization like the pros do. I don't know. Anyway, see my attached tutorial.

What is the class and range of your images? Are they uint8 (0-255), or uint16 (0-65535), or double?
Zip up your images and attach the zip file and let me know what intensity range should be each color. Like what values should be green, what values should be yellow, etc.
