The civil rights movement of the 1960s was a major influence on Alston. In the late 1950s, he began working in black and white, which he continued up until the mid-1960s, and the period is considered one of his most powerful. Some of the works are simple abstracts of black ink on white paper, similar to a Rorschach test. "Untitled" (c. 1960s) shows a boxing match, with an attempt to express the drama of the fight through few brushstrokes. Alston worked with oil-on-Masonite during this period as well, using impasto, cream, and ochre to create a moody cave-like artwork. "Black and White #1" (1959) is one of Alston's more "monumental" works. Gray, white and black come together to fight for space on an abstract canvas, in a softer form than the more harsh Franz Kline. Alston continued to explore the relationship between monochromatic hues throughout the series which Wardlaw describes as "some of the most profoundly beautiful works of twentieth-century American art."
