You can't look at the Web, you're looking at a monitor or at a sheet of paper. :-) The same color may look different on * a CRT type monitor * a LCD type monitor * a hardcopy done by a color laser printer * a hardcopy done by a color ink pee printer * ... 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. GRB and CMY are parts of the CIE specified space (see CIE diagram), but they don't have all the colors in common. There are colors you can show on a CRT, but you cannot print them 1:1. Anyway, the best reading contrast - black on white - looks boring on the web, and it stresses your eyes (too much light reflected / emitted). Furthermore, if you select a dark color for the background, LCD type monitors (that have a minimal light emission even if the color is pure black) may look too light, while a CRT type monitor may display the color as dark as you intended (because when it's black, the CRT does not emit any light, unless, of course, the base brightness is needlessly adjusted above the zero point). So much for physics, kids. :-) -- Polytropon >From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
