Designing with Coloured Light
Colour is a significant component of visual perception. It cannot be perceived without daylight or artificial lighting. LED and fibre optic lighting allows a multitude of design possibilities for emphasising or altering the lighting effect of rooms and objects with colored light. The term "colour of light" covers both white and coloured light. Warm white, neutral white and daylight white are derived from the white colour of light. The colored light covers the entire visible spectrum.
Compared to the primary colours yellow, blue and red, the colours amber and magenta appear weaker in their expressiveness. Yellow and red colours of light create a warm atmosphere in a room. Blue colours of light allow a room to give a cooler impression.

Colour Mixing
The RGB colour space is an additive colour model. The graphic shown here demonstrates this mixing of primary colours (red, green, and blue/violet). When combined in equal amounts, the additive primary colours produce white. Lighting, video, monitors and film recorders all use the additive colour model to represent colour. The human eye is based upon RGB colour; the eye has red, green and blue receptors whose signals are interpreted as colour by the brain. The primary colours are different for the computer RGB colour space than for the subtractive colour space.
