Zusammenfassung:	Systems and methods for determining illumination angle and viewing angle in color observation are described. The system includes an optical capturing device to acquire an image of its surroundings and a processing unit. When operated, the processing unit executes the following steps: identify a position of a light source in the image acquired by the optical capturing device; identify a position of a viewer in the image acquired by the optical capturing device; determine a first angular position of the light source with respect to the optical capturing device and a second angular position of the viewer with respect to the optical capturing device and provide the first angular position and the second angular position to define an actual viewing geometry.
