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 ... . > > This is due to the nature that these devices use different color > spaces (RGB, composed additively, CMY, composed negatively), and > most of them even aren't calibrated.

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.

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.
