What is the nickname of Jackson Pollock's 1950 painting 'Number 1'?

The nickname of Jackson Pollock’s 1950 painting “Number 1” is “Lavender Mist.”

Pollock painted the work in the summer of 1950, during his celebrated mature period of poured, dripped, and spattered painting. He worked on unprimed canvas laid on the floor of his barn studio in Springs, Long Island, using oil, enamel, and aluminum paint applied with sticks and hardened brushes.

The title “Lavender Mist” was not Pollock’s original designation. He had increasingly used numbered titles, and Clement Greenberg supplied this descriptive nickname. Despite the name, the National Gallery of Art notes that the painting contains black, blue, white, silver, russet, and orange rather than literal lavender paint.

It is often confused with Pollock’s similarly monumental works “Autumn Rhythm,” “Convergence,” and “Blue Poles.” “Lavender Mist” entered the National Gallery of Art’s permanent collection in 1976 after being owned by Pollock’s friend Alfonso Ossorio.
