Abstract
An apparatus, and method of use thereof, for multiangular visual evaluations of color properties of paint color samples which contain metallic flakes, comprising a cylindrical or semi-cylindrical shaped body capable of securing a color sample panel upon the central axis, wherein the circumference of the body has a partially glossy or mirrored reflective surface, and also has one or more marks indicating specific aspecular viewing angles relative to the plane of a color sample panel, thus allowing for improved correlation between visual and instrumental color evaluations of coated surfaces which contain metallic flakes.
