This document discusses an investigation into how color is associated with emotions like happy and angry in photographs. The author will examine works by Hector Sos, Gillian Wearing, and Kyungwoo Chun to analyze how these artists use color in their photos to express emotions. Hector Sos creates paper masks for portraits that use color and paper details to suggest feelings. Gillian Wearing photographs people holding signs with their inner thoughts, using lack of facial expression with messages. Kyungwoo Chun uses blurred portraits and bold colors that the author thinks could emphasize emotions when combined with colored backdrops.
