Definitions for Colour from the web

1. The interaction between the way our eyes work and the way light falls on objects creates the phenomenon of colour. We are capable of distinguishing between 10 million nuances of colour, although there are only 11 basic colour terms in the English language - black, white, red, orange, yellow, green, blue, purple, pink, brown and grey. Since the 17th century, scientists and artists alike have recognised that colour is important in designing and selling products.

2. The property of an object which is dependent on the wavelength of the light it reflects or, in the case of a luminescent body, the wavelength of light that it emits. If, in either case, this light is of a single wavelength, the colour seen is a pure spectral colour; but if light of two or more wavelengths is emitted, the colour will be mixed. White light is a balanced mixture of all the visible spectral colours.

3. Colour in drinking water may be due to the presence of coloured organic material, or metals such as iron, manganese and copper. There is no direct link between colour and health effects, however, consumers prefer water with a clear appearance therefore a limit of 15 true colour units (TCU) is recommended. EPCOR regularly produces water at <5 TCU.
