Wendy Edwards has taught at Brown since 1980, and a new solo exhibit pulls together four decades of paintings tied together, the show posits, by a luscious use of color. The main space features vibrant flowers and abstract geometric pieces in intense yellows, pinks, and oranges. Upper (2015, pictured) and Flourish (2019) are two standouts in a very colorful section of the exhibit. Less effective are the two dozen smaller works in the gallery’s lobby, some of which are interesting on their own (a Chinese landscape, a suggestive flower) but few of which seem particularly relevant to the idea of luscious color.
