"Up Around the Sun'' (diptych) (acrylic on wood), by Rose Olson. in her show "BRIGHT COOL and HOT,'' at Kingston Gallery, Boston, Nov. 29-Dec. 30. She paints on wooden panels patterned with natural grain, as the gallery says, "each specific to their character as a once-living tree. These patterns are as unique as fingerprints and as important to Olson as the colors she uses.''
