Calder similarly worked with painted metal sculpture in bold geometric forms, creating abstract works that celebrate color and industrial materials with a playful modernist sensibility closely aligned with Negret's approach in Sol.

Soto shared Negret's Latin American modernist vision, creating geometric abstract sculptures using industrial materials and bold color that reflect the same mid twentieth century constructivist spirit found in Sol.

Kelly's painted metal sculptures employ the same vocabulary of bold geometric abstraction and flat color fields seen in Sol, sharing Negret's minimalist precision and commitment to pure form through industrial materials.
