You have not applied a colormap to that image on the right. The one on the left has a colormap applied to it.

You did not show your code, so I don't know. By default imagesc() applies the jet (I believe) colormap. I find application of some arbitrary colormap that may not be appropriate annoying. I would guess that in your code you called colormap(gray);
