Diane Benoit du Rey works with painting and pigment, building compositions that move between the material and the immaterial — color gradients on canvas, sand surfaces dusted with raw pigment, and large-scale wall paintings that dissolve architecture into color.

Her works often unfold as gradients, bands of hue shifting so gradually that the eye struggles to locate where one tone ends and the next begins. This slow transition becomes the core of her practice: light not as subject, but as a threshold to be crossed.

Her paintings investigate perceptual phenomena : the altered states of vision, the boundaries of sight, and the fragile space between what is possible and what is limited.

Benoit du Rey is less interested in depicting the world than in questioning how it is seen: what we perceive, what escapes us, and what we only believe we perceive.
This inquiry has led her beyond the canvas into immersive wall installations, where color is not contained by a frame but spreads across walls and floors, enveloping the viewer within the same optical uncertainty her paintings propose.

The recurring gradient, the passage from one color into another, functions as her signature gesture, a visual anchor that returns across bodies of work in different scales and contexts. More than a formal device, it echoes her broader preoccupation with liminality: the moment of transformation itself, caught mid-movement, neither fully one thing nor another.

In 2023, she presented the institutional exhibition Hypnose at Espace Richaud in Versailles, and in 2025 her work was shown at major international fairs including Art Basel Paris and Art Basel Miami.
