Title:
INDEX FOR DETERMINING A QUALITY OF A COLOR
Document Type and Number:
WIPO Patent Application WO/2016/074801
Kind Code:
A3
Abstract:
The invention relates to a method for determining an index for characterizing a quality of a matching color tone of a paint in relation to a color reference, characterized in that colorimetric coordinates of the paint and of the color reference are determined for a number of measuring geometries using a spectrophotometer, color differences are calculated from the colorimetric coordinates of the paint and of the color reference for each of the number of measuring geometries and are normalized, and a pre-established assignment rule is used for assigning a value on a scale to a group of characteristic values calculated from the normalized color differences in order to determine the index.
