What was the period after Picasso's Blue Period called?

The period after Picasso’s Blue Period was called the Rose Period.

Picasso’s Rose Period generally dates from 1904 to 1906, following the darker Blue Period of roughly 1901–1904. It takes its name from the artist’s increased use of pink, rose, orange, and other warm tones, although the palette was not limited to pink.

The change also reflected a shift in subject matter. Instead of emphasizing poverty, grief, and isolation, Picasso increasingly painted circus performers, acrobats, clowns, and harlequins. His relationship with Fernande Olivier and his life among artists and performers in Montmartre helped shape this more colorful phase.

The Rose Period was not a complete break from Picasso’s earlier concerns: many of its performers still appear introspective or socially marginal. It led toward his African-influenced work and, soon afterward, the development of Cubism. Famous works from the period include Family of Saltimbanques, Girl on a Ball, and Boy with a Pipe.
