Aerosol art, often known as graffiti, is a form of visual art created using spray paint. Artists use aerosol cans to apply paint to various surfaces, including walls, buildings, and even canvases. This technique allows for vibrant colors and intricate designs, making it a popular medium for street art and urban expression. The practice of aerosol art emerged in the late 20th century, particularly in urban areas. It is often associated with the hip-hop culture and has been used to convey social and political messages. Many aerosol artists, like Banksy and Jean-Michel Basquiat, have gained recognition for their impactful works.
