Comment on What an unprocessed photo looks like
dusty_raven@discuss.online 1 week ago
I’m a little confused on how the demosaicing step produced a green-tinted photo. I understand that there are 2x green pixels, but does the naive demosaic process just show the averaged sensor data which would intrinsically have “too much” green, or was there an error with the demosaicing?

Yes, given the comment about averaging with the neighbours green will be overrepresented in the average. An additional (smaller) factor is that the colour filters aren’t perfect, and green in particular often has some signficant sensitivity to wavelengths that the red and blue colour filters are meant to pick up.
