Bridget Riley is an English painter associated with the Op Art movement. She was born in London and studied at Goldsmiths College and the Royal College of Art. In the 1960s, Riley began creating abstract works characterized by the use of black and white geometric shapes that created an optical illusion of movement and depth. Her work was shown in a number of major exhibitions and became widely known for their mesmerizing and disorienting effects.
In the late 1960s, Riley began to experiment with colour, introducing a range of hues into her work. This led to a new phase in her career, marked by the creation of more complex and dynamic compositions that explored the interaction of colour and form. Riley's work has been exhibited extensively in the UK and internationally, and she has received numerous awards and honors, including the Praemium Imperiale and the Order of Merit. She continues to live and work in London, and her art is held in the collections of major museums around the world.
