you should see the sin city comics
percepcion do you know what made sin city great? even when it was on black & white and the graphics sometimes where very simple.
what made the sin city graphics so cool is the composition and the use of the contrast. for example some elements have a black and a white part but you only see the white part in the black part of the background, so even when the contrast it is absolute (Black & White and no greys) the elements in the graphic have volume and depth perception.
you will understand what im saying if you see the sin city comics with attention, good luck.
