Picassos Blue Period lasted from 1900 to 1904. During this period, he mainly did monochromatic paintings typically with colors like blue and also bluish-green. He did use other warm colors, but it was occasionally done. These paintings happen to be some of the most somber painting done by Picasso in Paris; a Spanish influence is visible in these paintings.

The Blue Period paintings are based on a theme which is melancholy. After the death of his dear friend Casagemas, Picasso was in a state of shock. It was an unnatural death, a suicide. His friend shot himself with a gun. That marked the beginning of Blue Period.
