Colour Is Light. Intense monochrome areas of colour, radiant pigments, and multifaceted surfaces are the characteristics of the art of Winston Roeth (b. Chicago, 1945; lives and works in Beacon, New York, and Waldoboro, Maine).

He has devoted himself to abstract colour field painting since the 1970s, with the grid as a leitmotif running through his oeuvre; both are fraught with painterly memories of light, "a light that can jump out and grasp the beholders, a colour saturation that throbs with a deep glow", as the artist himself puts it. It emanates from the strata of paint in his pictures, encountering the light that, falling upon his works, molds their chromatic effect.

Roeth experiments with pure pigments, which he mixes by hand to make paints he applies in layers to diverse media including paper, aluminum, honeycomb, slate, and wood panels. The book documents a tour of an exhibition, presenting works dating from between the early 1990s and 2020.
