“Delta Lambda,” created by Morris Louis in 1961, is an abstract acrylic on canvas artwork, measuring 260.4 by 449.6 cm. This piece is part of the “Unfurled” series and is classified within the Color Field Painting movement. It is housed at the Cleveland Museum of Art in Cleveland, Ohio, United States.
The artwork features wide, flowing bands of color, predominantly positioned at the two lower corners, converging towards the center, yet leaving a significant portion of the canvas as negative space. The colors range from vibrant shades of red, yellow, green, and blue to muted tones of brown and gray, creating a dynamic yet harmonious visual experience. The composition is characteristic of Color Field Painting, focusing on the colors themselves rather than on shapes or forms, thus evoking an emotional response through its pure abstraction. The use of acrylic paint allows for sharp, clear demarcations between the colors, contributing to the clarity and intensity of the presentation.
