Hovering between industrial material and optical illusion, "(Gradient Painting #50)" from 2014 presents Mark Hagen's distinctive investigation into surface, perception, and the nature of painting itself. Acrylic pigment moves across a synthetic foil ground laid onto raw hessian, the whole construction anchored by a titan frame anodised with diet cola, a characteristically deadpan material choice that introduces an element of pop culture chemistry into what might otherwise read as austere minimalism. The result is a work that refuses easy categorization, sitting at the intersection of process-based abstraction and conceptual object-making, with the gradient serving not merely as aesthetic device but as a record of the conditions under which the painting came into being. At 184.5 by 123.5 centimeters, the work commands a substantial physical presence, the scale amplifying the slow, almost cinematic shift of color across the picture plane. Hagen, who divides his practice between Los Angeles and Europe, has consistently built his gradient paintings around questions of translation, asking what is lost or transformed when pigment meets unconventional substrates and when industrial processes are folded into the vocabulary of fine art. The hessian backing, visible at the edges where it folds over the support and bears the artist's signature and dating in his own hand, makes the construction of the work legible, inviting the collector to read both the front and the back as equally meaningful surfaces. This is a work for collectors drawn to painting that thinks rigorously about its own limits. The anodised cola frame is not a novelty but a conceptual anchor, grounding the gradient's visual softness in something acidic, consumable, and decidedly contemporary. The piece is signed and dated verso, and is offered without a frame, allowing the object to be encountered on its own terms.
