To me, the idea of a zero-width line would mean non-printing, so I
would avoid it. In fact, when I print tables and charts, one of the
things I experiment with is quite thin lines and not 100% black, as
they tend to make tables ugly and more cluttered.
I agree. Even with 0.02-inch thickness and 170-170-170 (light gray)
color, the grid lines come on too strong. I'll get around to trying
0.01 inch one of these days, and if that's still too much or LibreOffice
doesn't allow it, a yet lighter gray.
Color perception is complex and tricky....[snip]...I've
longed for much better color gamuts for monitors for a long time.
Perception [... snip...]
When it comes to monitors, the actual tint (or hue) of the red phosphor
isn't pure red. Not only isn't it 100% saturated red, but it's often
not red (on most old domestic CRT TVs it actually verged towards
orange). Likewise, with the blue and green phosphors not being 100%
mono-chromatic, and not being precisely the same tint on each screen.
Apart from meaning you couldn't get pure, or accurate colours, it meant
each screen looked different. You get similar impreciseness whether
it's CRT, plasma, or LCD.
Monitors generally handle white to intermediate saturation very well.
It's high saturation that they can't handle, especially in the green to
cyan range and the red to violet/purple range. I've known for many
years that 255-000-000 is orange-red, not red. What I've most been
wanting is an excellent high saturation true red, and high saturation
purples and violets. Mixing a little blue into "red", say 255-000-015
makes for a good red (not orange-red) hue, but the result noticeable
lacks saturation.
I'm actually quite impressed with how well our visual system adapts
(within limits) to the weaknesses of both monitors and printouts.
