Juan Carlos Callejas is a Colombian artist. He lives and works between South America and Europe. He worked alongside Peruvian artists associated with the Escuela de Bellas Artes del Perú, receiving early mentorship in studio practice and in the preparation of natural pigments. He continues to formulate his own materials, grinding pure pigments sourced from Colombia and developing bespoke binders. Rather than relying on standard grounds, he often builds a signature fiberglass mesh support engineered in the studio, which lends the surface transparency, tension and durability. Across layered, mixed-media fields he stages a precise dialogue between abstraction and figuration. Portraiture and scenes from daily life surface and recede through glazes, scrapes and transparencies, with latent images that become legible as the light shifts, at times recalling double exposure.

His work has been presented in Colombia and internationally, including Murinsel and LKH West II in Graz, Gallery F37 and the Volkshochschule Tempelhof-Schöneberg in Berlin, the Club des Résidents Étrangers in Monaco, Msheireb Gallery and Park Hyatt in Doha, Fundación PONS and Cuatro Torres in Madrid, Criolla Library in New York, the Centro Cultural de Cali and venues in Buenaventura, and a solo exhibition in Tokyo curated by Keigi Suzuki. Forthcoming projects include a presentation at Kunsthaus Köflach in Austria. Works by the artist are held in private and institutional collections across South America, Europe and Asia.
