red, green, blue, yellow, none of those colors really exist. It’s a convincing sensation. Qualia, filters or whatever.

so my favorite color doesn’t exist, not out there, outside my head.

other people experience the same sensations, the problem is fairly universal across the species, and beyond maybe to some extent.

fortunate really the cows out there grazing in the meadow are not contemplating this.

they don’t torture themselves with trying to will the green grass to be red, and get a headache.

how lucky are they, the cows.

So, you are in transition, again?

Me too, sort of. Last week I asked myself “what is your favourite colour?” and found that i didn’t have one.

I almost have to invent colours.

It sort of depends on the purity of the pigment, colour swatches from the paint shop are not reliable enough.

PS, trying to colour-match green is a huge headache.

The light also changes all the time, right now we are headed towards the month of May when most motorists have trouble with the angle of the sun.

There is a wikipedia article on colours that don’t exist. See if i can find it (LOL). Here it is.
https://en.wikipedia.org/wiki/Impossible_color

I also suspect that paint colours have improved dramatically in the past 40 years, My favourite colour would be on the Taubman/Dulux colour chart. Not accessible using Chromacryl paints.

I’m not particularly impressed by any colours on the computer screen, so suspect that my favourite colours are outside the rgb triangle. The colours on the following chart are fake, illustrative rather than accurate.

Furthermore, colours look so much better when I take my glasses off.

There’s another aspect to colours. Being Duetan (deuteranomaly). I don’t see much difference in colour between the two copies of this image. Do you? I see the red on the top one as being a bit redder. When I look closely, I can see that the bottom red is noticeably bluer/greener/greyer.

I suspect that my favourite colour would be monochromatic. I wish there was a way to check this, using for instance a bright incandescent globe, slit and prism. ;-(

The figure below is a comparison of the spectral sensitivities of L and M cones from normal trichromats (N), protanomalous trichromats (PA), and deuteranomalous trichromats (DA). Cone spectral sensitivities were taken from DeMarco, Pokorny, & Smith (1992).

Notice the separation between the L and M cone spectral sensitivities among normal trichromatic, protanomalous, and deuteranomalous observers. The separation between the two in normal trichromats is about 30nm, whereas it is much smaller in protanomalous and deuteranomalous observers. This smaller separation translate into a smaller L-M signal when we calculate the difference between L and M cone signal for each wavelength. The figure below shows relative L-M signal (response) as a function of wavelength. Note that the L-M output by protanomalous and deuteranomalous observers is significantly attenuated compared to that of normal trichromats.

So perhaps, just perhaps, my favourite colour is near-monochromatic centred on either one of the peaks of the DA L-M response spectrum, specifically 535 and 625 nanometres.

That would make them Fluorescene Green and orange-amber.
