The whole point was that there is physical combination of wavelengths that induces pink sensation but there is none for this new olo, this is why i think it is not a property of light but purely a human sensation.
Comment on The ‘Profound’ Experience of Seeing a New Color
wkk@lemmy.world 1 week agoDid 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:
shrimps have more cones because they’re dumb
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 invalidates what we might call a “color”. By his logic “pink” shouldn’t be considered a color, which I disagree with!

What are you referring to as linear? AFAIK human perception is very much non-linear, which is why we have color spaces like OKLAB.
