Drew and Roz,

In the additive color scheme, such as transmitted light, black is the
absence of all colors and white is the sum of all colors.  In the
subtractive color scheme, such as in inks and other reflective light
schemes, black is the sum of all colors and white is the absence of all
colors.  So you need to specify which color scheme you are using when
you make blanket statements about black and white. <grin>

Philosphically, you may be right.  Unfortunately, my eyes aren't
philosophical about it.  Black, and all dark colors for that matter,
have visual "weight" that overpowers white.  So on a black page with
white print, the background overpowers the text.  At least, that's the
way *my* vision works.

That's what I thought (though I think you have your last sentence
reversed...books are black on white...).  White on Black is letting your
eye's see what's there, not what's NOT there.  (Since Black is the
absence of all color, and white is the presence of all.)

Psych studies have actually shown that the human eye differentiates
light on dark more easily than dark on light and a dark background
(making up, as it does, most of the screen) should cause less strain to
the eyes, being less bright.

However, I think that we find reading white-on-black easiest because
we've all been habituated to it from reading books.
