1. A lighting arrangement configured to provide light of a desired color comprising:
- a plurality of light sources, each light source configured to emit light of a respective color that, when mixed, is perceivable as the desired color,a light detector configured to receive light reflected by a color reference surface having a specific reference color, and configured to provide a signal indicative of said received light, wherein the signal is provided in response to inserting the color reference surface into a slit, anda controller configured to analyze the signal from the light detector and thereby being capable of recognizing the color of the received light as the color of the reference surface, and configured to control the light sources in response to the signal provided by inserting the color reference surface into a slit such that the desired color of the light provided by the lighting arrangement corresponds to the color of the color reference surface.

Abstract
A lighting arrangement provides light of a desired color. The arrangement includes light sources that each emit light of a respective color that, when mixed, is perceivable as the desired color. A light detector is configured to receive light reflected by a color reference surface having a specific reference color. A controller is configured to analyzes a signal from the light detector and recognizes the color of the received light as the color of the reference surface. The controller controls the light sources such that the desired color corresponds to the color of the color reference surface.

16. A method for providing light of a desired color comprising the acts of:
-
controlling a plurality of light sources to emit light of a respective color that, when mixed, is perceivable as the desired color, receiving light reflected by a color reference surface having a specific reference color, providing a signal indicative of said received light in response to pointing a pointing device to the color reference surface, analyzing the signal and thereby recognizing the color of the received light as the color of the reference surface, and controlling the light sources such that the desired color corresponds to the color of the color reference surface as determined by the analyzing act from the signal obtained by pointing the pointing device to the color reference surface. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A color control device for controlling a lighting arrangement to provide light of a desired color, said lighting arrangement comprising a plurality of light sources, each light source configured to emit light of a respective color that, when mixed, is perceivable as the desired color, said color control device being characterized by:
-
a light detector configured to receive light reflected by a color reference surface having a specific reference color, and configured to provide a signal indicative of said received light, and a controller configured to analyze the signal from the light detector and thereby being capable of recognizing the color of the received light as the color of the reference surface, and configured to control the light sources in the lighting arrangement in response to inserting the color reference surface into a slit such that the desired color corresponds to the color of the color reference surface for providing the light of the desired color corresponding to the color of the color reference surface. - View Dependent Claims (24, 25)
