So you're saying that the "white" on my [monster] CRT is not the
same as on a future LCD Display? rats:) --I can't see much
difference in my new laserjet from my HP500 DeskJet, but then it
wasn't a main concern ... .

I took all 5 quarters of physics, like most of us, but never got
far into optics. And certainly, nothing like *this*. the
quality of my writing is much more important that the colors of
typeface or background. But this is an interesting side-bar.

Really! So far, in my tests [staring at a CRT], I find an
off-white reads most easily against a very dark blue. 000033;
or whatever 333366 is. Still experimenting.
