I meant superpose on the graph CIE colorimetric standard observer functions yadda yadda etc etc for our entertainment or enlightenment.
and actually, if one has a scene measured by a teleradiometer, or a decent multispectral cam, one can take the raw data from the transmission spectral measures and do a spectrum band by band product with the image data and derive a simulation of the way a scene would be seen through that instrument. Etc etc. eg see how a deer in foliage would appear in the early morning light, or a visiting canari doing a siesta on my neatly clipped and well watered french lawn at high noon.
numbers themselves are total sh*te until you contextualise them with the psychophysics of color perception, supplied in this instance by a fairly developed discipline called colorimetry.
The link to the paper does not work for me... I get a topic not found error. If you post a citation I could try google scholar. Thanks!
