Coloured accent lighting and coloured background lighting changes the effect of objects in the room. The colour saturation of the object increases in the foreground when the background brightness is decreased. Blue colours seem to recede into the background, while the chromatic effect makes magenta come to the fore.
Lighting effects can be intensified using coloured light. Strong colour contrasts increase the brightness contrasts. High brightness contrasts likewise increase the colour contrasts. Natural overall effects arise due to warm colours of light and filter colours such as "Skintone", magenta and amber, or due to cold colours of light such as sky-blue and night-blue.
