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.
