199. We Use Deep Blue . . .

We use deep blue to tell a desert canyon's depth at twilight. --Use warm red to remark upon a last sliver of dusk visible through haze, clouds, or diluted fog. --Use green to see where refugee groups of trees have survived that onslaught of our colorless phenomenon: development. --Use yellow so often for caution that now we see daffodils as warning: Here comes another Spring, which we'll fill with our history.
