Carol Aronson-Shore’s Portsmouth paintings raise classic New England architecture from the merely charming toward the classically beautiful. Aronson-Shore accomplishes this by infusing her “architectural landscapes,” as she thinks of them, with assertive elements of abstraction, still life, and figuration, carefully arranging and editing geometric shapes and colors. At the center of it all is Aronson-Shore’s feeling for light, both its drama and its serenity, and always its colors. Most often this light is the radiance of early morning or late afternoon, when slanted sunbeams can illuminate a burst of blossoms or splash pink and violet shadows on a salt-box wall.
