Four horizontal maroon-purple forms seem to float and vibrate against an intense field of red-orange. This Mark Rothko painting (specifically the artwork Four Darks in Red from 1958) is a quintessential example of Abstract Expressionism and Color Field painting, where the focus is on the emotional power of color rather than representational imagery. The soft, blurred edges of the rectangles create a shimmering, ethereal effect, making the shapes appear to advance or recede depending on how long one stares at the different color segments.
