Hi Penny,

I have some thoughts regarding the difference in recorded color spectra. According to some other theories in the course of evolution of the human species which is still on-going our senses are continuing to develop as well. Some studies show that man may not have always been able to see the same color spectrum, that pastels and colors at each end of the spectrum are a more recent development of our sensory abilities. And as our perception of physical reality and energy changes we will be able to see completely different frequencies, previously thought to be undetectable to the human eye.

Looking at the recent push in symphony orchestras to change tunings to ever higher frequencies I can see some correlations to that theory. Not only is sound and light speeding up, but time seems to as well. Or maybe it's just our relation to all of the above. Maybe more a metaphysics question than straight forward physics.
