About colour rendition of light sources. The balance between simplicity and accuracy.
The CIE Colour Rendering Index (CRI) is a well-known descriptor for the colour rendering properties of light sources. Being a single number the CRI is a comprehensible figure of merit. The accuracy of the CRI in predicting specific colour rendering aspects is relatively low. CRI is an average of only 8 colours and accounts only for the size of the colour shift. Several new suggestions for an improved description of colour rendering have been done. All these suggestions had one thing in common: the description of colour rendering gets more complicated. In this paper we will present a new way of analysing colour shifts and discuss the effect of the colour sets and the effect of narrow band spectral power distributions on the accuracy and simplicity of colour rendering information.
