Colour quantization, uniform quantization

Hi there, I'm working on a project on colour quantization and I'm a little lost with matlab (complete beginner). The method of quantization I'm working on is uniform quantization which splits the red and green axis into 8 segments and the blue axis into 4 giving 256 regions. Then finds the average colour in each region. I'm wondering how I would go about this my code so far for this:

image = imread(ImageName);

red = loadedImg(:,:,1);
green = loadedImg(:,:,2);
blue = loadedImg(:,:,3);

I honestly have no idea as I'm new to matlab! Thanks in advance!

Don't call your image "image". Call it loadedImage or something because image() is the name of a built-in function. So then just do a for loop to get the 3D gamut. Attached is an example.

Sorry but I don't quite understand what 3D gamut does? Would you mind explaining in terms of the example you provided?
