Abstract

One aspect of Computational Aesthetics is the finding of harmonic colours for the objects in a scene. Although the obtained degree of colour harmony is a subjective criterion, experience shows that on average human observers tend to have quite similar responses to individual colour stimuli and their combinations. This observation is the basis for what is commonly referred to as Colour Order Systems (COS), which aim to arrange colours in a fashion such that users can intuitively select individual colours – or even whole sets of them – according to some criterion. However, when dealing with a spectral rendering system, the use of traditional colour space COS to obtain pleasant associations of colours becomes impossible, principally due to metamerism. An interesting problem would be the derivation of a COS for spectral data which includes the ability to deal with fluorescent colours, the indirect goal of such a metric system being the selection of aesthetically pleasing colour values for a spectral renderer.
