Wearing Blue and Seeing Red:
The Use of Color in Punch-Drunk Love
Using color to heighten emotion or show character traits in film is a delicate thing. In the wrong hands, color can be overused to the point where its obviousness can detract from a movie. Paul Thomas Anderson makes obvious use of color in Punch-Drunk Love, but wisely chooses to avoid using it as the only source for depth in the film. While combining colors in different points of the film with other aspects such as three-dimensional characters, lighting, humor, and sound, Anderson creates layers of depth that bolster one another for the good of the whole.
From the get-go, the film assaults the viewer with unconventional use of color. Barry Egan sits alone at his desk, clad in an unusually bright blue suit. It is here that one of Barrys character traits is exposed and accentuated by color. Like the hue of his suit and the blue painted stripe on the wall behind him, Barry recedes in a cool, unexcited manner. Isolated from the outside world, Barry is calm and comfortable as he clears up the confusion he has about the Healthy Choice airline promotion. It doesnt take long to bring him out of his comfort zone, however. After finishing his phone call, Barry walks down the alley outside of his business to the main road. As he stands there the quiet blue morning is interrupted by a red car crashing down the road in front of him. Suddenly a red cab pulls up, drops a harmonium in front of him and speeds off. After this bizarre turn of events, Barry is shown facing the camera, but the serene dark blue that surrounded him moments before is replaced by glaring white. The fairly collected Barry shown on the phone is gone, replaced by an awkward, out-of-place man who is clearly confused and uncomfortable. The blue suit comes into play again, but unlike earlier when it blends in with the surrounding blue paint by his desk, it exhibits Barrys feeling of being out of place in the situation when contrasted with the white that nearly envelopes him. White is a central color throughout the film, combining with the blue suit to demonstrate Barrys inability to blend in and feel comfortable. Another example of this is a situation after a window-smashing tantrum at his sisters home. Surrounded by white cupboards, Barry tries to confide a problem to his brother-in-law. Barrys sad attempt to glean psychological help from a dentist is once again stressed by the juxtaposition of his bright blue suit and the white room they stand in. He just cant seem to handle himself in the harsh social world of his life, and he stands out as does his suit.
