Dimming, colour control and various distributions of light allow the colour of light to be altered. When combined with a specific light distribution, the perceptual focus in the room can also be changed. The contrast in colour and in brightness matches the importance of the sculpture. The warm colours of the wallwashing and accent lighting replicate the warm atmosphere at sunset. However, using several luminaires casts multiple shadows and creates a contrast to the daylight, which has the sun as its only source. By using lighting control, the atmosphere can be adjusted to produce very different results and, in contrast to daylight, can be maintained producing a specific lighting effect.
