Any Other Color Besides Gray?

There is a lot of gray in this film from the Manhattan buildings to Gregory Peck's wardrobe, but I'd like to look at the colors that characterize the women in his life. When we were watching the film, Agatha pointed out that she hated Betsy's outfits throughout the movie. I noticed, too, that they seem quite drab, even for a 1950's housewife. In the majority of the film, Betsy wears a combination of gray, brown, beige, and orange - not the happiest of colors. I wonder if this was meant to parallel the "mundane-ness" of the life she felt she lived. Her dour and boring attire matched her dour and boring home (and life). It is only when Betsy is happy to be settled in the old mansion that she finally decides to wear pale pink, a more pleasing and happy color. In contrast, when we first see Maria in flashback form, she is wearing a bright teal dress, brimming with brightness and passion, like it's wearer. The use (or lack thereof) of color does separate the two women in my mind - and Tom's decision for a passionate affair, leaving his dull life behind him.
