|Ellsworth Kelly, Green Blue Red, 1963, 67.5 x 90 inches|
Here's an excerpt from the curator's notes on this piece, which resides at the The Broad contemporary art museum in LA:
Green Blue Red abstains from the balance and harmony of traditional painting and reflects an impulse to build a surface of visual tension out of the contrasts of color and shape and the containment of an edge. Kelly’s works of this period depict the jarring difference between colors and the unusual placement of shapes, energizing the visual experience and creating a disorienting optical effect. The green rectangle and blue oval are vibrant and foreign against the red background. Kelly does not construct balance or resolve; he creates compositions that are alive in their idiosyncrasies.
