Now for colour. It is a quirk of the uman eye
that you can get the
visual effect of any paritcular colour by seeing the appropriate
amounts of red, green, and blue light.
This is only approximately true. There are two reasons it's only approximate.
I think you're right. However, most, if not all, video monitors mix red,
green and blue light for each pixel, so you need essentially 3 signals to
control the intensities of those.
