Thanks for the feedback!

Do you know if he is protanopic or deutanopic? Would this friend happen 
to be on IRC any time? I'd love to get direct input from someone that 
actually has color-blindness (I don't) in order to make the best 
possible scheme.

That I'm not sure what the problem is. Any thoughts/suggestions? (Or did 
he mean telling selection apart from not-selection?)

Did he said normal text was OK though? I'm a bit confused because it 
looks like the titles are just using the view color, i.e. I would expect 
them to be about equally good/bad.

Hmm... yup. On the one hand, that's partly intentional (it's supposed to 
look "disabled" after all), but I see the point. I toned down the 
disabled effect, so this should be improved.

If my protanopia simulation is at all working (which I don't trust at 
all ;-) ),  I actually find some of the alternate color roles very 
illegible... I guess that's good news for the default scheme though :-).

Dichromats still seems likely, and of course most of those are the 
"red/green" kind, where a blue/yellow theme makes sense. (The current 
simulation code I have is using blue/yellow for tritanopia as well, 
which is different from the pink/blue I see most places, so I *really* 
don't trust that.)
