Years ago I was adjusting the color balance on a modern CRT computer monitor.
I had made a wallpaper in MS Paint of a color bar test pattern mimicking the NTSC pattern.
I found that when I turned the green and blue channels to zero, that the red no longer looked red, rather an orange with a sepia cast.
Since then, I've wondered if CRT color TV sets abt computer monitors was delivered with a very blue color balance (9300K versus about 5500K of daylight illumination) because the "orange-sepia" yttrium red phosphor looks red against such a bluish image (comments most welcome).
