White Black Grey. For the handsome exhibit The Other Primary Colors — White Black Grey, at Space Gallery, the included artists have limited themselves to neutral tones. Everything is elegant, aloof and well carried out, and all of it owes a debt to either minimalism or pattern painting. The show, organized by Marks Aardsma, begins with small prints by Tonia Bonnell in which the artist uses identical elements to create different abstract groupings. Across from these are Nancy Koenigsberg's three-dimensional wire-mesh bas-reliefs, with geometric compositions that have powerful graphic qualities. Opposite the information desk are some remarkable oil paintings by Carlene Frances, who, based on these incredible pieces, should be lots better known. Behind the gallery's dog-leg and into the back, Aardsma has paired Corey Postiglione with Space owner Michael Burnett, who in addition to running the gallery is also an accomplished abstract painter. The show reaches a crescendo of quietness in the double-height back gallery, where Aardsma has included her own pieces alongside works by David Sawyer. Through October 20 at Space Gallery, 765 Santa Fe Drive, 720-904-1088, www.spacegallery.org. Reviewed October 5.
