The best way is in the composite manager. I was to implement a plugin
for compiz to do that, but compiz just breaks my X server in a dual-head
environment (the second screen don't have DRI). And also, compiz/beryl
cannot be the only option.

Metacity seems to be implementing some composite support, but I don't
know about its state.

So gnome-mag seemed to be the clean path at the moment.

For what I've seen so far, it depends on two variables.
1) what kind of colorblindness you have.
2) what kind of confusion the image creates.

It seems that the hue-shift filters (both positive and negative) are the
most usefull for the most cases, but there are still cases where you
need a "stronger" filter... the saturation/dessaturation filters can do
that job.
