My question could have been clearer, I meant that the relative contrast
between fore and background colours using Linux Colours is OK so I can
see grey on black fine, and the difference between a colour and the
same one bold is also obvious.
I've used some cheaper crts that were just gross, and in the past found
that the quality of LCDs were highly variable and mostly unrelated to
price (this seems to have settled now though).
One of the things I don't like about black background is that on all monitors
the background seems to "crowd" the glyphs -- the markings seems more
slender than when the colors are reversed.* With small fonts (I like high
resolution settings for other reasons), this makes the lettering hard to read.
You seem to know what to do in most cases and how to achieve it, so I
don't know if my favourite colour schemes will help you much. However,
have you considered an eye test for colour sensitivity? A large number
of males are under-sensitive to certain colours and it's apparently
hard for the person to detect it in themselves.
I'm glad it seems so, since I teach computer science at the university level.*
But I was hoping to get samples and suggestions of how others have dealt
with this.* I've been muttering under my breath about this for a few years
now and I thought it likely that others may have taken action.
As for vision: I have such an exam yearly.* I always see the numerals in their
samples, and nobody's ever mentioned color insensitivity. Nevertheless, it's
possible it's vision-related since it works this way for me on all monitors, and
in my work I see a lot of monitors.
