Title (EN) DIFFRACTIVE COLOR SYSTEM
(FR) SYSTEME DE COULEURS DIFFRACTIVES
Abstract:
(EN) The present invention relates to a method in a diffractive color system, which color system specifies visual color effects, target colors, which are formed by mixing together two or more diffractively produced primary colors. According to the invention, the primary colors and the characteristics of the elementary gratings used in producing them are selected in such a manner that they produce the desired exact primary colors particularly in the application-specific lighting and by taking into account, when required, the color of the substrate material and/or other background separately. The invention also relates to a diffractive color system implementing the method, as well as a diffractive component producing the mixed target color. Further, the invention relates to a product containing one or more diffractive color effects.
(FR) La présente invention se rapporte à un procédé dans un système de couleurs diffractives, ledit système spécifiant les effets de couleurs visuels, les couleurs cibles, qui sont formées par mélange de deux ou plusieurs couleurs primaires produites de manière diffractive. Selon l'invention, les couleurs primaires et les caractéristiques des réseaux élémentaires utilisés dans leur production sont sélectionnés de manière à produire les couleurs primaires exactes souhaitées particulièrement dans l'éclairage à application spécifique et en tenant compte, au besoin, de la couleur de la matière de substrat et/ou d'un autre fond séparément. L'invention se rapporte également à un système de couleurs diffractives mettant en oeuvre le procédé, ainsi qu'à un composant diffractif produisant la couleur cible mélangée. Par ailleurs, l'invention se rapporte à un produit contenant un ou plusieurs effets de couleurs diffractives.
