background, with color to show which side is which, easier to read.
To me, the contrast between the white and the grey in his image:
does not seem as obvious or clear as it would be if it were black
lines over grey (or another pale color) with a white background.
I'm not sure why this is so for me. I do have a mild astigmatism (see
link in more recent message from Al Black) and I certainly grew up
with origami diagrams on paper, not electronic form, so perhaps it's
just visual habit... I have experimented, myself, with different
display settings over the years (I still use bright text on a black
background for coding) but most of my display settings are black
text/lines on white, so perhaps it's just what you get used to.

A biological element ... everyone's eyes filter light
differently, often causing some very serious challenges. "Light" is an
element assessed in learning and productivity style. In relation to Gerardo
question - due to this bio factor the color dilemma is one that usually will
not find a "best" for all answer. One solution, should anyone be interested,
can be explored at http://irlen.com/ These filters and or lens have
offered functional improvement to many folks that I have worked with.
