Is there possibility to extend section on XYZ colorspace, explaining it comes from experiments on how human eye receptors receive color (they obviously do not use technological rgb notation), because it was such source of confusion to me? Also, saying primaries are most possible colored points (greenest green in G direction, reddest red in R direction, etc) in choosen colorspace might be useful , at least I found those remarks clarifying illustrations nicely. Example of colormatrix settings also might be useful. Revision 2, after Andrew's suggestions. Talking about human vision and colormatrix settings are beyond my skill set and also too much for an introduction. I have put up a link that may be of interest. https://peteroupc.github.io/colorgen.html
Thanks! man ffmpeg-filters (for ffmpeg 5.0) Says about colormatrix example For example to convert from BT.601 to SMPTE-240M, use the command: colormatrix=bt601:smpte240m
