Analogous colors in the background.
I am intrigued by the effect of the color in this ink and watercolor sketch of the musicians. The background colors flow from orange to red to red/purple to purple. The colors used on Ken Barry, the saxophone player who was being featured at that moment, are yellow and blue, the two colors on either side of the analogous colors of the background. The yellow and blue colors bring the figure of Ken forward. I get the impression of a color wheel lying on its side in the position of the viewer being “green”, the one color on the outer ring of the basic color wheel that is not represented in the painting.
