Assuming the image is truly a colour image and not an indexed image:
imshow(input_Im(1:128, 1:128, :));
If you don't say you want all three colour planes (the : in the 3rd dimension) you only get the 1st one.

This might also be interesting to see what happens if you leave off a dimension when indexing arrays. http://blogs.mathworks.com/steve/2011/03/22/too-much-information-about-the-size-function/
