Abstract

When a light scene comprises multiple colors of light, not all white light is suitable for matching the scene. A method is provided such that a white point is determined for each color in a set of colors, to create a set of white points. A single white point is then determined based on the set of white points. This allows, for example, a user to select a light scene (e.g. a romantic scene featuring red colors) for a living room, such that lighting devices contributing to the scene emit colored light. A functional lighting device (e.g. reading light) can then emit white light, determined according to the method, to provide more functional light (e.g. light suitable for reading) that matches the scene (e.g. warm white instead of cold white).
