Interesting...also Jack and Lureen were so much alike. They both went against the status quo...Lureen riding broncos at the rodeo, being an independent woman, being good at business deals, all things that were not seen as the stereotypical female role that the society they lived in accepted. Jack was a man who showed his emotions, dared to dream about a better life outside and a bigger world, it is not only about Jack being openly gay, but about Jack's personality as a whole. He went against what society wanted, he didn't care what anyone thought. Ennis and Alma, on the other hand, they just accepted everything. Ennis we know was not really the person society wanted, but he hid it, and only showed that part to Jack...everywhere else he pretended to be the tough guy or he hid his emotions. He made no effort to change the status quo aside from being in the relationship with Jack, which of course he thought he kept it a well-hidden secret. Alma also accepted the status quo, she was the docile church-going girl, a house-wife. She later married Monroe, who is better able to give her that life than Ennis was. We see her pregnant again, seeing her main role in life as a mother and homemaker. Very different from Lureen. The more neutral colors symbolize that maybe, the other colors are bolder, the bolder characters wear the bolder colors. Also, tying into this is the colors Ennis wears are the earth-tone colors, showing how he is on the ground, so to speak, tethered to the ground, bound, while Jack wears the sky and water type colors, showing he's a dreamer who flies above the ground, always searching for something else, not being earth-bound. Jack and Lureen represented change for the better, more freedom, progress, while Ennis and Alma represented the status quo...parochial, do what is expected of them...no matter how miserable that same was making everyone feel. The status quo represented that conformity to a small-minded society, the unhappiness it caused, but people like Ennis and Alma feeling powerless in it, "if you can't fix it, you have to stand it"...no matter how miserable it makes them, they just accept.
