Visual theme of black and white

Just saw it again and wondered if others had picked up on the color schemes associated with the older generation? You may have noted that the adults are almost invariably cast in black and white. From their home decor to their clothes: black and white. Just the way they saw the world; clear choices, no gray areas. In stark contrast to Benjamin’s uncertainty about his own future. They tried to foist this narrow world-view off on their son, pushing him towards success and “plastics”. Symbolically, they even stuff him into the black scuba suit, and the camera pans out to show him, a black figure, floating against the white sides of the pool, motionless and paralyzed, neither up nor down, frozen in his dilemma. Later, when he is well into his affair and feeling all grown up, a “man” of the world, he takes to sporting the snazzy wrap-around sunglasses even at night, which are: black. He’s seeing the world through the colored lenses of adulthood. He only takes them off when he sees Elaine (my god, how I loved Katherine Ross) crying in the strip club, and immediately drops his cad persona and reverts to the kid that he is, which wins her over. I don’t remember if I picked up on this when it first came out, but nobody else seems to ever have noticed it; and now I see it everywhere when I view it again. How about you?
