Pablo Picasso’s defining artistic styles evolved throughout his career, initially characterized by the Blue Period reflecting themes of sorrow and poverty. This transitioned into the Pink Period, focusing on lighter subjects and warmer tones. However, his groundbreaking work in Cubism, co-developed with Georges Braque, transformed modern art, emphasizing abstract forms and multiple perspectives. Picasso’s innovative techniques and relentless experimentation redefined artistic boundaries, making him a central figure of 20th-century art.
