Herren's abstract expressionist work invites the viewer into a world of riotous color and visceral experience. He first creates a deeply personal painting and then covers the work with tinted pumice. That granular surface is strategically removed by the artist to allow for a glimpse of the artist himself. Herren simultaneously explores the complexity of self-identity and human relations and challenges the viewer to sit with the tension of wanting to see more, wanting to know the "true colors," wanting to wipe away the course veneer that hides the true soul of another.
