Static-Dynamic Gradation 1923. Paul Klee / This watercolor reflects the artist's preoccupation with color relationships. Here, outer dark colors surround pure luminous ones in the center. In this work Klee devised a systematic movement, progressing from dark-hued brownish squares, which he dubbed "static," toward the clear-colored ones, which he called "dynamic" by virtue of the contrasts they offer.
