Paul Thomas Anderson and legendary cinematographer Robert Elswit give us a lesson on how to use a color palette and illumination schemes in a film. From the different shades of blue (to portray sadness, but also depth and faith), reds and grays, to playing with a whole gamut of colors in a supermarket, both filmmakers transcend the common use of color to make a proper use of tonality in relation to different feelings, tensions and connections. A masterpiece of photography, Punch-Drunk Love deserves to be studied over and over.
