Intertesting research, but it is not a colour. It is a human's visual sensation created by giving the brain unusual inputs. If you take the same light and measure it spectrum, it is not new.
Did you know we only experience pink as our red and blue cell receptors being stimulated at the same time? There is no pink wavelength.
Captain Obvious would like to chime in: (sorry 😅)
Every color that we see is created by different types of receptors being stimulated together. A linear combination of three of these types. Arguably there isn't really a wavelength that only stimulates one type of receptor exclusively as their absorbtion areas overlap - so it isn't even that precise to call one receptor the "green" receptor as it sees a continuum of wavelength (of which a lot are also detected by the (so-called) "red" receptor.
It's a little egg-and-hen-problem with the naming here.a way out of it would be to only speak about spectra if it's in the physical realm and color of its in the percetral realm.
I saw the following meme the other day on that topic which I found amazing:
On the other hand I hope my point was clear about pink being perceived as a color when it doesn't exist as a singular wavelength on the electromagnetic spectrum: something the person I was responding to was seemingly arguing that it then invalidates what we might call a "color". By his logic "pink" shouldn't be considered a color, which I disagree with!
