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.<br>
> Example of colormatrix settings also might be useful.<br>
Revision 2, after Andrew's suggestions. Talking about human vision and<br>
colormatrix settings are beyond my skill set and also too much for an<br>
introduction. I have put up a link that may be of interest.<br>
