Kelsey Brookes’ Gradient Paintings comprises the artist’s latest series exploring new ways to reflect how the perception of art is underpinned by biological systems and chemical reactions occurring in nature and the human body.  The content of these paintings stem from the scientist Heinrich Kluver’s discovery of form constants, which are a set of geometric patterns observed during altered states of consciousness or hallucination. There are four categories: lattices, cobwebs, spirals, and tunnels. His experiments analyzed subjects under the influence of psychoactive compounds like mescaline and their visual experiences – all followed one of those form constants.
