Which O'Keeffe painting features a cow's skull decorated with red, white, and blue?

Cow's Skull: Red, White, and Blue features a cow's skull decorated with the colors named in its title.

Georgia O'Keeffe painted the work in 1931 after becoming fascinated by animal bones found in the New Mexico landscape. The skull is presented vertically against a blue background, with red and white accents that evoke the colors of the United States flag.

The painting belongs to a major group of New Mexico works in which O'Keeffe transformed bones into monumental, carefully arranged forms. She did not treat them only as symbols of death; she also emphasized their sculptural shape, weathering, and relationship to the immense landscape.

This painting is often confused with Skull with Calico Roses, another O'Keeffe work from 1931. The titles identify different compositions: one combines a cow's skull with patriotic colors, while the other places a skull beside flowers.
