Clyfford Still’s piece PH-129 shows his great use of abstraction while also using only colour to explain the piece. He uses yellows, reds, and some spots of brown and white. Compositionally, the piece shows a foreground and a background through the use of colour. For most of his works, he chose colours at extreme ends of the colour spectrum. As Still put it, his paintings could be described as "life and death merging
in fearful union."
