The light reflection value of color in paint.
A 1930 trade publication issued by the New Jersey Zinc Company, a paint and pigment maker, offering technical guidance on how colour reflects light in paint for industry and building professionals. The photographs show factory interiors where paint and pigment products were made and packed, with workers at long benches and rows of machinery under a high timber-beamed roof, giving a designer a plain record of early twentieth-century industrial workspaces.
