Be it in daily life or in manufacturing industries, in retail or in the private sector, many different light sources are in use today, such as sunlight, incandescent lamps, fluorescent lamps, energy-saving variants and, more recently, LED lamps. Each of these light sources has different spectral characteristics that strongly influence the human perception of colour. If the same colour is viewed under different illuminants, the colour impression varies to different degrees.


This is referred to as colour constancy. When two colour samples look identical under one illuminant, but change under another illuminant, this is known as metamerism. This occurs when the two colour samples were produced using methods that differ in one or more ways, including raw materials (e.g. inks/colourants and substrates), imaging methods (e.g. spray paint, wipe-on stains, direct inkjet printing), and finishes (air dry, UV cure, varnish or laminate overcoat, etc.).
