Hm, can you help with creating a good set of colors?
There are a number of programs around which can help with this. I
use Color Oracle: http://colororacle.cartography.ch/
It sits in a Gnome panel, and will temporarily change your entire
display's colours to simulate three different kinds of colour
blindness.
While I do like the concept of this application, it seems
to be closed source and (probably?) does not take choosing
colors off my shoulders.
Well, at least it's free (beer) if not free (speech). Its algorithm
is published, though, so if someone felt so inclined they could
probably write something free (speech). I haven't seen anything open
source yet. Basically, the general advice is to avoid distinguishing
colours solely in the red and green components; red, green and yellow
can all be confused by colour blind males. I have seen suggested
spectra for use in charts for colour blind people, and the
predominating colours are blue and brown.
Still not free, but the following web site probably helps you do what
you want:
http://wellstyled.com/tools/colorscheme2/index-en.html
Click on its "triad" button, and it automatically picks three
contrasting colours which work in all forms of colour blindness
(including the extremely rare case of totally monochromatic vision).
For example:
#5CB85C
#B85CA1
#E6A173
is one such set, and works quite well for normal vision, because they
are greenish, purplish and beige-ish respectively.
