Jean,
There are various types of colour-blindness - red-green is the most common. I did a quick Google on "design for colour-blind" and got several useful hits, mostly for web designers. The basic message is "don't rely on colour to get a message across", which isn't much help to you.
One way round this might be to allow the user to select colours for the different distinguishable syntax elements (I think this has already been suggested somewhere in this thread). And not to make it too complicated. I personally get a bit fed up with Frescobaldi's colours but being normally-sighted I can live with it.
Best regards,
Peter

In principle (and practice) women DO suffer this problem. It's caused by
a defective X chromosome so, like haemophilia, the majority of sufferers
are men. If however a colour-blind man marries a carrier woman, any
daughter runs a 50-50 risk of being colour-blind.

chosen to have enough contrast to the white
background to be readable even for those
with impaired vision. Since I am not such a
person, I have been checking the scheme against
WCAG recommendations. The color with least
contrast has 6.15, which is quite a bit
above the WCAG AA level of 4.5. This means that
even someone not discerning colors at all
can read such highlighted code.I am colorblind (which BTW means that it's hard to distinguish certain
colors, not that everything is gray).
Sorry if I gave a wrong impression. I didn't
mean that everything actually looked gray, just
that it was the extreme imaginary case encompassing
all types of colorblindness (I think there are
different ones, right?).
I can't see a difference
between the blue and the purple, but this doesn't cause a problem for
me -- I just miss some of the highlighting, which is unavoidable. The
bold terms jump out at me, but the coloration seems reasonable. All
in all, the scheme seems reasonable to me.
Thanks for the input! That's reassuring.
Best regards,
Jean
