Rhode Island-based artist Nadia Haji Omar makes beautiful chromatic abstractions. Drawing from her Syrian, Indian and Sri Lankan heritage, Omar’s practice is informed by rigorous studies into Islamic and traditional Chinese art and the decorative and religious symbolism and architecture of her childhood home in Sri Lanka. Sticking to a mild, washed-out pastel color palette, Omar weaves tiny, meditative mark-making into elegant Tamil and Sinhalese symbols and letters. Her works convey a wonderful sense of materiality and lightness that underlie the artist’s spirituality and devotion to the preservation of traditional mythology. At Kristen Lorello through May 25.
