Abstract

La invención se refiere a una imagen en color (IG) que comprende: una primera capa (10) que incluye una estructura holográfica que forma una disposición (29) de pixeles (30), cada uno de los cuales incluye subpixeles (32) de colores distintos; y medios de modulación de color configurados para seleccionar el color de los pixeles (30) al modificar la contribución colorimétrica de los subpixeles (32) entre sí en los pixeles (30) para revelar una imagen en color adecuada. Los medios de modulación de color pueden comprender: regiones de la estructura holográfica, denominadas regiones destruidas, que son destruidas localmente por láser; medios de enmascaramiento colocados frente a la disposición de pixeles para enmascarar localmente todos o parte de los subpixeles; o medios de amplificación colocados frente a la disposición de pixeles para amplificar localmente la luminosidad de todos o parte de los subpixeles.
