Purple Haze and other rabbit holes …

Carried over from http://www.dotheton.com/forum/index.php?topic=44407.120

Color blind cannot see purple, but the reality is, no one actually sees purple. Purple does not exist in the spectrum. It is a construct of the brain to deal with a combination of red and blue. There is no spectrum analyzer that can identify purple. Red is one enf of the spectrum, blue is the further end. There is no wavelength of purple.

Google it, there are other sources...

I end this line of posting …

The original statement was "no one actually sees purple" which is demonstrably incorrect.

Our colour vision is such that we see a range of colours, both spectral and non-spectral. Spectrums, colour gamuts and YouTube videos etc. are just obfuscations.

Did you guys know that Robins can see magnetic fields?
Yeah think about that one for a minute.

Robins can see magnetic fields …

… and quite a few insects can see into the ultraviolet, some can see polarization.

Yeah but visual perception of photons isn't foreign in any way.
Visual perception of a magnetic field is just bonkers and gives us an idea of just how limited our perceptions are.
