Jules Olitski was one of the principal exponents of Colour Field painting, which involved using flat expanses of colour, and rejecting illusions of depth and the emphatic brushwork of Abstract Expressionism. Olitski's large scale canvases are covered in delicate mists of colour that give the works an all-over unity and a sense of continuation beyond the frame. The paintings have an ethereal quality, appearing to dematerialise the canvas surface. Olitski said he would prefer 'nothing but some colours sprayed into the air and staying there.'
