This vibrant woodcut by Damien Hirst features nine large colored spots arranged in a three by three grid on a white background, each circle rendered in a distinct hue including crimson, teal, purple, pink, navy, yellow, red, orange, and pale blue. Part of the celebrated series 12 Woodcut Spots, this work exemplifies Hirst's signature exploration of color relationships, repetition, and the interplay between scientific naming conventions and pure visual experience. The title references the essential amino acid tryptophan, continuing Hirst's longstanding practice of naming spot works after pharmaceutical and biological compounds. As a signed limited edition of only 48 impressions on Somerset paper, this is a highly collectible print from one of the most prominent figures in contemporary British art.
