William Perehudoff CM SOM RCA (April 21, 1918 – February 26, 2013) was a Canadian artist closely associated with colour field painting.

[9] In November 2009, several of Perehudoff's murals were successfully removed from the executive suite in the former Intercontinental Packers plant.

Perehudoff painted them in 1950, and the abstract silhouettes are considered the last remaining examples of purist cubist art from that period.

[10] Ian Hodkinson, a retired art conservator, was brought in and used a special method to remove the acrylic paint from the plaster intact.

[13] In 2010, a travelling retrospective titled The Optimism of Colour: William Perehudoff was curated by Karen Wilkin for Saskatoon’s Mendel Art Gallery.
