Abstract: La présente invention concerne un procédé de détermination d'un paramètre spécifique à la coloration personnalisée de poils d'un individu donné, le procédé comprenant les étapes de : - réception de grandeurs représentatives d'une première couleur cible et d'une première couleur initiale dans un espace colorimétrique, - détermination d'une composition de produit cosmétique en fonction des grandeurs reçues et d'un modèle de rendu colorimétrique, - application d'un produit cosmétique ayant la composition déterminée sur les poils à colorer de l'individu pour obtenir des poils colorés, - évaluation de la couleur des poils colorés pour obtenir une grandeur représentative d'une première couleur finale dans l'espace colorimétrique, et - détermination d'un paramètre de déviation colorimétrique spécifique à l'individu en fonction des grandeurs représentatives de la première couleur finale et de la première couleur cible.

Abstract: The invention relates to a method for determining the color of a cosmetic product on a skin model, the method including steps to: - for a plurality of wavelengths, supply experimental points giving diffusion and/or absorption values for several mixes of a given concentration of one pigment in another pigment, each mix corresponding to different given concentrations, and - use a physicochemical model capable of predicting interactions between pigments passing through experimental points to obtain the curve giving the diffusion and/or absorption for each wavelength as a function of the given concentration of pigment in the mix of pigments considered.

Abstract: This method for determining a skin colour of a region of interest of a user, comprises: - importing, from an image library (LIB) of a user computational device (APP), at least one image (IMk) comprising a representation of the region of interest of the user; - performing processing (TS) of said at least one image (IMk) with a machine-learning model (AI_TS) suitable for providing, for each imported image (IMk), a numerical value (ClrEstm_k) representative of the skin colour of the region of interest present in said at least one imported image (IMk); - performing evaluation (EVAL) of the skin colour of the region of interest on the basis of said one or more numerical values (ClrEstm_k) of each imported image.
