Alan Charlton is a contemporary British artist who creates Minimalist paintings and installations. In the late 1960's, Charlton decided to only create gray paintings, citing the emotional qualities and mutability of this particular color. Geometric forms, such as a single triangle or rectangle broken into modular elements float on these monochromatic grounds. Of these conceptual works Charlton has said, “I want my paintings to be: abstract, direct, urban, basic, modest, pure, simple, silent, honest, absolute.” 

John Gibson Gallery was founded in New York City in 1967 by John Gibson (1933-2019). The gallery is recognized for the Minimalist, land art, arte povera, conceptual artists and European artists it represented and whose careers it helped launch. The gallery closed in 2001.
