The invention relates to a method for determining the colour perception of multi-layer dispersive materials or biological materials for layer thicknesses that are respectively selective, by the determination of the diffuse reflectance based on the respective intrinsic optical parameter using Monte Carlo simulations and taking into consideration the measurement geometries, anisotropy and the dispersion phase function in order to correctly take into account the multiple internal dispersion of the material. The colour effect is calculated from the diffuse reflectance based on the various colour systems in accordance with different algorithms.

L'invention concerne un procédé pour déterminer la perception des couleurs de matières dispersives multicouches, telles que des matériaux ou des substances biologiques, pour des épaisseurs de couche respectivement sélectionnables, par détermination de la réflexion spectrale, en fonction des paramètres optiques intrinsèques respectifs, au moyen de simulations de Monte Carlo, et avec prise en considération des géométries de mesure, de l'anisotropie, et de la fonction de phase de dispersion pour tenir compte, avec exactitude, de la dispersion multiple interne des matières. L'effet des couleurs est calculé à partir de la réflexion spectrale, en fonction des différents systèmes chromatiques selon divers algorithmes.
