During a recent visit to the Art Institute of Chicago, I spent some time in front of the famous Chagall windows. I have always related well to his striking use of deep blue. This got me thinking about my own long-running use of blue in my work and my awareness of how significantly the color of light can change from one geographic location to another. Any landscape artist worth their salt understands this language of light and color. The deep blue shadows of a Wisconsin valley will vary by season and time of day. The color of light on a Wisconsin ridge top will be very different from the mountain colors in the thin, blue-black Colorado air. I credit my long years of experiencing the wide variety of Wisconsin's beautiful land and waters to my having such a deep relationship with blue.
