MATLAB: MATRIX REPRESENTATION OF COLOUR IMAGES

You are seeing the difference between RGB ("Truecolor") images, which are rows x columns x 3, compared to a Pseudocolor images, which are rows x columns plus a something-by-3 colormap:

[canimg, canmap] = imread('canoe.tif');
size(canmap)
ans =
   256     3

In order to get a pseudocolor image displayed in color, you need to activate its colormap:

   colormap(canmap);

This is done on your behalf if you ask to imshow('canoe.tif')
