Titled the «Wooster» series for the location
of this revelation, these geometric forms with hard edges furthered the artist's exploration
of shaped canvases, formalist elements
of the line, and
literal as well as depicted
shapes.
Among the dominant trends in the Post-Painterly Abstraction are Hard - Edged Painters such as Ellsworth Kelly and Frank Stella who explored relationships between tightly ruled
shapes and edges, in Stella's case, between the
shapes depicted on the surface and the
literal shape of the support and Color - Field Painters such as Helen Frankenthaler and Morris Louis, who stained first Magna then water - based acrylic paints into unprimed
canvas, exploring tactile and optical aspects
of large, vivid fields
of pure, open color.
