The "Rose Period" refers to a phase in the artistic career of Pablo Picasso from 1904 to 1906. During this time, Picasso's work transitioned from the darker themes of his Blue Period to lighter, warmer colors, predominantly pinks and reds. The subjects often included circus performers, harlequins, and acrobats, reflecting a sense of optimism and joy. This period is characterized by a softer, more romantic style, showcasing a blend of realism and abstraction. The change in palette and subject matter marked a significant evolution in Picasso's artistic expression, paving the way for his later developments in modern art.
