These colour studies focus on the use of 250 colours to compose the abstract. The reality of using 250 colours is a considerable feat in advanced colour management and composition. colpol developed a special colour wheel palette measuring 1.5x 1.5 m in size on which to mix and display all 250 colours with notation. There were four trials before the final studies emerged.
Using a single-day painting strategy, the oil paints and mediums were mixed in the early morning with fast drying agents and painted on board. In the late afternoon the remainder of the colours were added in fat. There are two studies displayed in each triptych.
