Chronicle Books has formed Chronicle Chroma, a new imprint that the company said will publish books on the visual arts and pop culture. The imprint, which will release its first four titles this fall, will be led by Steve Crist and Gloria Fowler, who were the publishers of Ammo Books, which specialized in the publication of art and architecture books.

Chronicle president Tyrrell Mahoney said Crist and Fowler will “bring their unique editorial vision and California aesthetic to this new imprint.” Chronicle Chroma will be based in Los Angeles, and Chronicle Chroma will put out 20 titles annually. and Its list will also include deluxe limited editions of select titles, as well as postcard sets inspired by the books.

The imprint’s four launch titles are: Ballerina Project, which showcases Dane Shitagi’s photographs of more than 50 ballet dancers; Silver. Skate. Seventies., a collection of never-before-seen photos of the 1970s Southern California skateboard scene by photographer Hugh Holland; Tree of Life, a monograph by Tim Biskup, whose work spans animation, drawing, painting, and sculpture; and Dream Baby Dream by photographer Jimmy Marble.

The creation of Chronicle Chroma is the second imprint started by Chronicle this year. In March, the publisher announced the launch of Chronicle Prism.
