Specifying different colour for each block

I got the below coding from demo in one site where the image is divided into blocks..
clc;
close all;
rgbImage = imread('im9.bmp')
rgbImage=imresize(rgbImage,[256 256]);
imshow(rgbImage);
set(gcf, 'units','normalized','outerposition',[0 0 1 1]);
drawnow;
[rows columns numberOfColorBands] = size(rgbImage)
blockSizeR = 64;
blockSizeC = 64;
wholeBlockRows = floor(rows / blockSizeR);
blockVectorR = [blockSizeR * ones(1, wholeBlockRows), rem(rows, blockSizeR)];
wholeBlockCols = floor(columns / blockSizeC);
blockVectorC = [blockSizeC * ones(1, wholeBlockCols), rem(columns, blockSizeC)];
if numberOfColorBands > 1
ca = mat2cell(rgbImage, blockVectorR, blockVectorC, numberOfColorBands);
else
ca = mat2cell(rgbImage, blockVectorR, blockVectorC);
end
plotIndex = 1;
numPlotsR = size(ca, 1);
numPlotsC = size(ca, 2);
for r = 1 : numPlotsR
for c = 1 : numPlotsC
subplot(numPlotsR, numPlotsC, plotIndex);
rgbBlock = ca{r,c};
imshow(rgbBlock);
[rowsB columnsB numberOfColorBandsB] = size(rgbBlock);
plotIndex = plotIndex + 1;
end
end
I have 16 blocks as shown in link

I don't know what mean value i means in regard to a color image. Please explain. Also, you should know by now how to format your question into code and non-code parts, and to make links to web sites.
