White Light is one of Pollock's last paintings and the only one he completed in 1954. He made it in part by squeezing paint directly from a tube onto the canvas evident in the sculptural white and black tendrils of paint that constitute the top layers. He also used a brush, creating subtle marbling effects by manipulating wet paint in certain areas. Though Pollock was tormented by an artistic block he would never overcome, White Light sparkles, and one reviewer described it as having "a blazing, acrid and dangerous glamor of a legendary kind."
