Last week's posting was about bright, clashing colors. This week is about subtlety. The cabbage plants at the garden center took me by surprise. I think of cabbage leaves as being green with a silvery sheen. What a surprise to discover a carpet-sized spread of plants whose leaves were splashed with tints of yellow, pink and lavender. Green may not be simply green when you stop to look more carefully. How far can green be "pushed" with the addition of other colors and yet still be considered green? This is an artist's question, one that can be a mystery, a goal and a mainstay in the ways we use color in our art.
