The use of different colour temperatures and/or coloured light augments the spatial differentiation or accentuation of objects. A more intense colour impression can be obtained by illuminating a body colour with the same colour of light. To create lighting effects with an intense atmosphere, it is necessary to work with saturated colours and intense colour contrasts. Variations in the colour temperature primarily arise due to selecting light sources ranging from warm white to daylight white. Coloured light is best produced by RGB colour mixing luminaires or by using colour filters.

Differentiation using brightness contrasts

When the lighting design relies exclusively on white light, contrasts are produced by differentiating the brightness levels. If the design uses incandescent lamps, dimming can also slightly shift the colour temperature towards a redder tone. White light provides a neutral basis for lighting generally, which when using appropriate light sources, results in very good colour rendition. Perception focuses on the three-dimensional effect obtained by light and shadow, making this is the key to effective modelling.

Differentiation using colour temperature

A subtle differentiation can be developed in any area using a full range of colour temperatures. Using a cold light colour intensifies perspective and creates an open feeling of space for the objects accentuated with warm white light. This type of contrast can be achieved by using the appropriate lamps or alternatively by using colour filters.

Differentiation using coloured accent lighting

A coloured accent can be used to add emphasis to individual objects against a background illuminated in neutral white. The more saturated the light colour, the stronger the resulting contrast, whereas coloured light creates the impression that the object itself is coloured. The use of colour filters allows light colours to be produced or changed with flexibility and ease.

Body colour and white light

Whereas white illumination can bring out the colour of the material with good colour rendition, coloured lighting increases the effect or exaggerates it.

Body colour and coloured light

Coloured material which is illuminated using light of the same colour intensifies the colour impression. The diffuse coloured light reflected from the surface lends a greater colour intensity to the whole room.

Atmosphere through colour: scene 1

Using coloured light can alter the appearance of white objects and transform the neutral coloured room concept into a world of intensive colour. Luminaires with variable light colours can be incorporated within a scenography with a changing colour composition. Saturated colours produce an intensive effect when combined in the classic colour contrasts. The focus of perception lies less with the three-dimensional effect produced by shadows than with the interplay of colours and atmosphere.
