Blue And Gray by Mark Rothko (1962)

Two soft rectangles drift against each other. Blue And Gray, 1962, keeps the edges blurred, as if seen through morning haze. A pale cobalt square floats above a rectangle of cool gray. The colors don’t meet; they breathe, separated by a whisper of white space. No brushstrokes show, only the slow fade of pigment into linen. Hang it where the light shifts—above a low sofa or between two windows—and watch the gray deepen as dusk arrives.
