<DIV></DIV>>I believe all raster screens use RGB additive colours, however
<DIV></DIV>>vector graphic screens(draws only a single line at a time) like the
<DIV></DIV>>old Tektronix colour graphics terminals, used subtractive CYM
<DIV></DIV>>colours. This only got messy when you were trying to add 35 mm
<DIV></DIV>>cameras to capture the screen output to slides. I used this back in
<DIV></DIV>>80's for IBM main frame 3270 colour terminals. The 35 mm terminal
<DIV></DIV>>adapter was expensive at the time around $5000.

<DIV></DIV>>>Drew and Roz,

<DIV></DIV>>>In the additive color scheme, such as transmitted light, black is
<DIV></DIV>>>the
<DIV></DIV>>>absence of all colors and white is the sum of all colors. In the
<DIV></DIV>>>subtractive color scheme, such as in inks and other reflective
<DIV></DIV>>>light
<DIV></DIV>>>schemes, black is the sum of all colors and white is the absence of

<DIV></DIV>>>Philosphically, you may be right. Unfortunately, my eyes aren't

<DIV></DIV>>>That's what I thought (though I think you have your last sentence
