Does a camera profile allow interpolation for colors that are not there? At
the start of this thread the person was asking about photographing under
sodium vapor lamps. If he was talking about low pressure, those lamps are
basically monochromatic yellow lamps. There is very little energy in the
blue end of the spectra. This means you cannot make a image look normal
unless you add colors that are not there.
This is admittedly a extreme example, LPS lamps are not something you are
commonly gong to come up against, but it does in fact describe part of the
problem here.
