Computational Models of Colour Contrast

In the previous chapter, colour contrast was examined as phenomena within the art domain. In this chapter, we review computational models that might be employed to define these phenomena. In the engineering domain, there is not a standard measurement model of lightness, saturation or hue contrast. All existing models would probably be better regarded as application tools rather than as descriptions of basic visual function. Colour contrast is broadly understood as being one of two things: a relationship between two things (i.e. simple contrast) or the variance of a property within a single thing (i.e. complex contrast).
