Abstract: The following procedures are included: a procedure (1) for measuring a metallic paint color by a multi-angle spectrophotometer and storing the multi-angle colorimetric value Lab* of the paint color, a color classification code to which the paint color belongs, and a computer graphic image in a memory of a computer and a procedure (2) for calling a metallic paint color to be retrieved (this is referred to as the metallic paint color concerned) from the memory by using a paint color name as a keyword. Moreover, in the case of a new color not stored in the memory, the color is measured by a multi-angle spectrophotometer and stored in the memory in accordance with the procedure (1). A screening function (3) is included which previously narrows down paint colors whose approximate colors will be computed by using color classification codes when computing an approximate color of the metallic color concerned.

Abstract: A computing system and associated methodology of evaluating and matching colored sparkle appearance of coatings containing at least one effect pigment type are disclosed. The methodology processes a digital image of a coating sample obtain pixel-specific sparkle point data and pixel-specific background data, both of which are formatted in accordance with an advanced color appearance model that corresponds to human color perception. A colored sparkle visual scaling value is calculated from the pixel-specific data, wherein the visual scaling value indicates colored sparkle characteristics of the coating sample. The visual scaling value of the coating sample is compared against the visual scaling value of a previously-characterized candidate coating specimen. The results of the comparison are used to determine how well the candidate coating specimen matches (in colored sparkle characteristics) the coating sample.
