The colour of light is determined mainly by the surface colour of the illuminated object. Warm white light is used to intensify warm tones, and cold tones are emphasised with neutral white or daylight white light. An impressive night-time atmosphere can be created with varying colours of light. Architectural proportions and structures can be accentuated and their spacial characteristics emphasised by varying the lighting levels. Coloured light on the other hand should be handled with care. An alienation of the natural tonal balance with the use of coloured light can attract a lot of attention, but is annoying in the long run and is furthermore architecturally unfitting.
