Abstract:
A method for retrieving a metallic paint color of an approximate color, comprising:a step of storing color classification codes of a plurality of metallic paint colors in a memory of a computer; a step of measuring the multi-angle colorimetric value CIE Lab* of a specific metallic paint color; a step of deciding a color classification code to which the specific metallic color belongs in accordance with the multi-angle colorimetric value CIE Lab*; a step of inputting the color classification code to which the specific metallic color belongs to the computer; and a step of retrieving a metallic paint color of an approximate color by applying approximate-color computation for computing a color difference only to a metallic paint color having the same color classification as the one to which the specific metallic color belongs among the plurality of metallic paint colors stored in the memory of the computer; said approximate-color computation comprising weighting multi-angle colorimetric value.
