The way I read the description of sRGB is that it is clipped in device space (with the possible implication that clipping is dependent on the values of components other than that being clipped), whereas what seems to be being said here is that clipping occurs in HSL space. Maybe the description of sRGB clipping needs to be clarified, as it it appears to imply that values outside [0,100] are have a meaning other than their clipped values. > All light sources stimulate the optic nerve.

But if you only add three components, the cross talk between receptors means that you will never be able to get all combinations of output from the three types of receptor. THe reference to light sources was because the colour of dye based reflective systems depends on the detailed spectrum of the illuminating source, making a source, where everything is controlled a simpler case.
