Espiral Laranja 

"Espiral Laranja" is a geometric abstract artwork by Brazilian artist Rubem Ludolf (1932-2010), known for his work in the Concrete Art movement. The work features a vibrant orange background with black, concentric squares that create a spiral effect. The use of simple geometric shapes and bold colors is typical of the Concrete Art style, which emphasizes structure, order, and pure visual experience. The precise arrangement and repetition of the squares create a sense of depth and movement within the composition, drawing the viewer's eye to the center of the artwork.
