    Ultraviolet Light (UV)

    Light energy not normally visible to the human eye, but which is present in natural daylight. UV energy has the ability to excite certain substances (dyes/pigments/chemicals) within a sample causing them to emit light in the visible spectrum, usually in the blue region. These substances are used in various products to brighten colors, particularly whites. It is necessary to include correct amounts of UV energy in a color matching system to allow for optimum simulations of natural daylight.
