actual fact what your eyes see is edges not "white" or "black". The rods
and cones fire when a change in the "lightbeam" that hits those cells occurs.
Your eyes make teeny weeny little movements all the time so you can discern the
edges that occur on static visual stimulii ( eg writing on a page). Thus the
argument of seeing what is or is not there is fallacious - you must have the
edges present in the stimulii to see anything. For years I insisted
that I preferred white on blue as the less eye straining computer screen layout
- now that my eyes have deteriorated to the point where I cannot read anything
less than 14pt time roman without glasses I have gone back to black on white -
and hate white on blue with a passion, especially on paper. In fact, I
dislike most web pages on principal regardless of colouring. Come to think
of it, computers are a bloody poor idea........ fades away into the (red on

<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>>>
<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>>>all

<DIV></DIV>>>Philosphically, you may be right. Unfortunately, my eyes
aren't
<DIV></DIV>>>philosophical about it. Black, and all dark colors for that

<DIV></DIV>>>have visual "weight" that overpowers white. So on a black

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

letting
<DIV></DIV>>>your
<DIV></DIV>>>eye's see what's there, not what's NOT there. (Since Black
is the

<DIV></DIV>>>Psych studies have actually shown that the human eye
