Typically using symmetrical compositions, Colman explores themes of human sexuality, societal hierarchies, life and death. He vacillates freely between figuration and abstraction, at times focusing on pattern to such a degree that it overwhelms any recognizable components in his painting; other times he privileges figures and narratives. Also producing sculpture and installation works, Colman incorporates a variety of media, including pencils, paper, wood, porcelain, plaster, glue, nails, and tape—typically using vibrant colors.
