Ellsworth Kelly’s Blue Black Red Green is a lithograph on Lanaquarelle watercolor paper. Overall, it approximately measures two feet tall and just over seven feet wide. The work is in horizontal orientation, meaning that its longest side runs parallel to the ground. A lithograph is a printmaking technique where an image is drawn on a flat stone or metal plate with an oil-based medium, then chemically treated so that when ink is applied, it adheres only to the drawn areas and can be transferred to paper to create multiple identical prints. The image in Blue Black Red Green shows a minimalist art composition featuring four colored diamond shapes arranged in a horizontal row against a white background. From left to right, there is a blue diamond, a black diamond, a red diamond, and a green diamond. Each diamond shape appears to be the same size and slightly tilted. They are placed in a perfect row at an equal distance apart, creating a simple geometric pattern. This overall arrangement creates a sense of balance while the slight rotation of the black diamond adds a subtle dynamic element to the otherwise symmetrical composition.
