The artwork “RED PANEL” by Alexander Calder, created in 1936, is a sculpture belonging to the Kinetic Art movement, specifically a mobile. As characteristic of Calder’s work, this piece encompasses both motion and abstract elements. This mobile features a dominant red panel as the backdrop with an array of abstract shapes and lines suspended in front of it, forming a harmonious and balanced composition. These elements include a sinuous black line, a grey organic shape with a yellow triangular detail, and two circular forms, one white and one maroon, all hanging by wires from a curved metal rod affixed to the top of the red panel. The components are designed to move gently with air currents, engaging the viewer’s sense of space and motion.
