"In a somewhat ironic turn of events, Campbell's initially approached Warhol to create an image based on their new product, and the result was a three-quarter view of a soup box on a square canvas. Warhol then took this idea and produced an entire series of smaller works experimenting with both size and color as well as with a range of soup flavors...yet what is particularly new in this series is the great degree of color change, from standard red, yellow and white to purple, magenta and lime green, or metallic copper and silver to hot orange and pink...the more intense the coloration, the less recognizable the Campbell's product becomes."
