The three well-known artists in Martha Daniels, Amy Metier, Betty Woodman represent three distinct generations of Colorado artists, even if the show's title listed them out of order. Woodman is the elder stateswoman, having lived in Boulder from the 1950s until a few years ago, when she retired to New York. Daniels came next, having moved to Colorado in the 1960s when she began exhibiting her work. Metier would be last, since she came along about a decade later. But the disparate work of these three artists fit together perfectly -- not because they're all women, though that's not irrelevant -- because all are master colorists. This compatibility, so hard to achieve in a group show, is a big reason this exhibit was one of the year's finest.
