Spray paint is a versatile, fast-drying aerosol medium known for vibrant colors, smooth coverage on diverse surfaces (metal, wood, canvas, paper), and its role in street art/graffiti, offering artists speed, portability, and unique control through different nozzles (caps) for detailed or broad applications, often used in mixed media for backgrounds or layering. While historically for graffiti, modern art brands offer low-odor, pigment-rich, water-based options for studio use, demanding practice for technique but enabling quick, large-scale art.
