monochromist

noun

1. An artist working in the monochromatic style.

   “His art connects to European monochromists like Yves Klein and Piero Manzoni and also to skeptical painters like Albert Oehlen and Christopher Wool, but it may be best understood as an Americanized, Warholian version of Arte Povera; Mr. Stingel often favors cheap materials (Styrofoam, for example), but instead of being distressed they are always brand new, industrial and somehow implicitly American.”
