Mark Rothko used color and brushwork to convey atmosphere and environment in his abstract works. An earlier painting from 1944, "Slow Swirl by the Edge of the Sea", depicts figures and shapes in a way that creates a contemplative mood using line, shape and color. His 1958 painting "No. 16 (Red, Brown and Black)" focuses on blocks of color that create a sense of space and reflection through his choice of hues and application of paint. The document examines two Rothko paintings to show how his abstract style evolved over time to immerse the viewer in the atmosphere he aimed to portray.
