Abstract

This invention relates to a method for matching a colour formulation to a colour shade model in the field of a colour- and/or effect-imparting surface coating. The reflecting surface of a colour shade, which is to be rematched, of a coloured surface coating is determined metrologically over the visible spectral region using a goniometric spectral photometer with variation of the angle of measurement. The associated standard tristimulus values and/or the vectors in the CIELAB colour solid which are derived therefrom are calculated from the measured reflection factors or spectral energy factors.
Those formulations and/or colour shades which exhibit reflection properties or properties derived therefrom which are the most similar to the measured colour shade model are subsequently identified from a formulation database by means of the reflection spectra or the colorimetric dimensional numbers derived therefrom. By means of a computer-generated effect matrix, the metrologically determined, angle-dependent colour difference between the desired colour shade, i.e. the colour shade to be rematched, and the actual colour shade, i.e. the colour shade corresponding to the nearest formulation from the formulation database, is minimised by means of a computer algorithm for function minimisation taking into consideration secondary conditions in the sense of the L2 standard, and a corrected formulation is produced.
