Complementary Colours

George Carlson, American, In the Shadow of the Sun, 42 x 42 inches

Subtle hints of pink lend radiance to the predominantly green palette. There's just the right amount of the complementary colour to create a vibration. Too much and the vibration becomes oscillation, and the sense of peace in the work is lost. The square format enhances the abstract qualities of the piece.
