The term 'Artist with a Blue Period' refers to the Spanish painter and sculptor Pablo Picasso (7 letters). Picasso is widely regarded as one of the most influential artists of the 20th century. His Blue Period, which lasted from 1901 to 1904, was characterized by a somber palette of blues and greens and a focus on themes of poverty, loneliness, and despair. During this period, Picasso produced some of his most iconic works, including The Old Guitarist and La Vie.
