When Los Angeles-based graffiti artist RETNA's work first appeared in the mid-nineties, what made it stand apart from the rest was its unique layering. His color palette was so intricate, so carefully chosen, his pieces often looked to have been daubed on with a paint-brush. Quite the achievement when you consider he was painting on walls, trains, bridges, and freeway overpasses in the black of night.Frequently inspired by images of females found in magazines and corporate advertisements, RETNA is especially known for embellishing existing fashion advertisements overlaying a classic style that recalls Mayan and Egyptian hieroglyphs, and even Byzantine religious mosaics.
