If I understand the experiment behind the development of the 1931 Standard
Observer, the answer has to be yes. I don't quite know how Guild & Wright
were able to maintain the light energy constant throughout the whole
spectrum in their respective experiments but they did, and at a *constant*
light energy level (equi-energy spectrum) my understanding is that longer
wavelengths were perceived as "darker" than medium or longer ones.
Or did I miss your point?
BTW, what does [TAN] stands for?
