The colour-matching functions and visual research.
The following points are examined: the problem of how to define the colour of a stimulus used in visual research; the limited relation of the colour-matching functions to the spectral sensitivity curves of the individual colour receptors in the retina; and the case for abandoning luminance as a colorimetric variable and lightness as a colour appearance variable.
