Orange and Green:
You stand in the green; roil, roll, fight, sweat, and faint in its infection. The orange sits in your toilet bowl, fumes of acid make you retch.
Blue and Yellow:
That's why envy is green, because you take the sadness of blue, and the joy of yellow and you get a manic, violent splatter.
Red and Pink:
Puppy dog love and bulging instinctive passion don't mix well. One is smiles and gentle kisses on closed eyelids, the other is sweat down tensed backs and barred teeth. A flower in a storm.
