Colors out of gamut with no extra processing

Ok so first, each pixel collects light within a given band (approximately Red, Green, or Blue) and outputs a number from (for the sake of argument) 0 to 1, proportional to the amount of light it collected. Any combination of pixel values at this stage have real physical meaning and so can’t really be outside of the CIE 1931 color space

Sorry, a bit over-simplified, I reckon.

For example, some cameras collect a little IR in the red channel and that really is “outside of the CIE 1931 color space”.

As you know, IR is not “light”.
