Today I consider color. I look outside and see green trees. But all the trees are not the same green. They range in intensity from deep, almost-black green hemlocks to pale, almost-yellow green birches. Today white plume-like clouds reach across an intense blue sky. But sometimes the sky is pale blue with a splattering of gray clouds, or blue with a hint of sunrise or sunset. To say the sky is blue doesn’t quite cover it.
