Sensible basic lighting is the basis of every lighting concept. Just like sunlight, this is mounted from above and thus creates an even basic lighting. It is essential to supplement these with other light sources, such as floor or table lamps. This means that the additional light source demands attention and supports the selective illumination.
In addition, the colour of the light plays a major role. Uniform light colours tire the eye and concentration decreases. Points of light and light-dark zones promote the mobility of the eye, as the surroundings are more attractive.
