They look green to me as well; as I do suffer with protanomaly, shouldn't my brain be adding in more of the missing red?

When "accomodating" my vision, I can see some "yelowish" colours ...

There is something I notice all the time when I'm working on a painting. If I put colors next to each other they look different depending on the combinations. Blue next to red looks different than next to yellow and so on.

Yeah only blue and green shows up. The heck? Maybe the guy uploaded the wrong picture or something.
EDIT: here's a better picture https://www.illusionsindex.org/i/grey-strawberries
Now although they say there's no red there actually is. You need red blue and green to make greys. that specific grey is
red 166
green 182
blue 181
So when you see the cyan, the red in the grey stands out. That's my take on it

Well, sort of. The image only 'contains red' in an RGB representation. What matters is the relative tristimulus values of the different colors in the image, and there are an infinite number of spectra that can result in any given set of tristimulus values*. You could mix up arbitrary pigments or wavelengths to get to a tristimulus ratio equivalent to the RGB color in the image and get the same effect. Tristimulus values are related, but not equivalent, to RGB values: Red, green, and blue make good primaries because they provide a gamut that covers most of the human visual range, but in terms of spectral colors, these do NOT correspond to the peak sensitivities of the color receptors in the human eye, which actually have fairly complex sensitivity spectra, meaning that the RGB representation of a color does not have a direct correspondence with that color's tristimulus values. (Actually, you'd need to specify *which* RGB representation, since there are many based on different primaries. Fun fact: many color spaces actually use as their primaries imaginary colors that the human eye can never perceive, because they make for a wider gamut than any set of three 'real' colors ever could)
* Except for those colors that lie on the spectral locus (monochromatic colors), for which there is exactly one spectral distribution (all of the photometric power concentrated in a single wavelength).
