The artwork, “Untitled (Red, Yellow, and Green Forms on a Purple Ground)” by Barnett Newman, belongs to the Abstract Expressionism movement and is categorized as an abstract genre.
This artwork depicts an array of geometric and free-form shapes rendered in distinct, bold colors such as red, yellow, and green against a purple background. A vertical green stripe runs through the center, breaking the predominantly purple canvas with its straight, contrasting line. Surrounding this central element are various abstract forms: a yellow triangle, a green square, and a yellow-outlined square. Additionally, there are red and blue forms interspersed throughout, adding depth and interest to the composition. The use of vibrant colors juxtaposed against the dark purple ground creates a visually dynamic and intriguing piece.
