As a member of the Regina Five and Director/Curator of the Norman Mackenzie Art Gallery (1958-1966), Ronald Bloore had a widespread influence on the artistic climate of Saskatchewan. He was instrumental in attracting Barnett Newman to lead the 1959 Emma Lake workshop and was one of the chief proponents of an international outlook in art.

Bloore was born in Brampton, Ontario, and received his initial education as an art historian. Starting in 1960, he began using universal symbols in his paintings to communicate ideas through formal means. His first paintings of this type were radiant sun explosions, and he later added crosses, wheels and stars. Yellow-Green Painting continues this exploration, making use of a grid to further draw attention to the two-dimensional surface of the painting. This work is an example of Bloore’s early artistic production. In 1963, he travelled to Greece, Turkey, Egypt and Spain, an event that changed his outlook, causing him to destroy much of his earlier work.
