A computational view of colour

The computational view of colour is that human perception and use of colour can be explored and explained as computations. The fundamental problem of colour is to explain how we see colours as relatively stable despite the fact that the light reflected into our eyes from an object varies dramatically with the light illuminating the object. Colour and computers have become much more intertwined in recent years as colour displays and colour printers have become more affordable. Since colour is a perceptual, not a physical quality, it is crucial to have a good model of how we perceive colour in complex environments if we are to get predictable results from these devices
