ABSTRACT:
A pressurized spray can contain a colorant coating stuff which varies in color intensity directly with the amount applied to a substrate, as for instance a photochromic material, is combined with a movable indicator of a color matching the colorant and graduated in depth of color (intensity) matching those applicable to the coated substrate. The indicator is mounted on the container and disposed in the line of operator vision when the container is functionally positioned so that the operator simultaneously views both the substrate and the selected indicator portion.
