Caption: Colour temperature spectrum. This spectrum shows how the overall hue of a source of visible light can vary in terms of a calculated characteristic known as colour temperature. The light produced by a source such as the Sun or a light bulb or candle will include a range of colours, but this can be averaged out to obtain a value for its colour temperature. This is expressed in Kelvin and here ranges from 1500 (red), through 3000 (yellow), 4000 (white), and 5000 (cyan), to 6000-8000 (blue). This covers the range from sodium bulbs to metal halide bulbs. For this spectrum with the temperatures labelled and with examples, see C011/6360.
