Snipping your detailed comments (thanks!), have you seen the Zion 
schemes? (They are installed by kdeaccessibility.) These were meant to 
be ports of the black/white high contrast schemes (admitedly, with a bit 
more color; it sounds like for 4.1 maybe I should tone down the 
difference of the various "extra" roles versus normal?).

I guess we are missing the low-contrast scheme. (I wonder, wouldn't it 
make more sense to turn down the monitor brightness? Not that I'm 
against making one as such, but it seems like monitor fiddling would 
help with e.g. images as well.)

Yes, that's exactly what I was aiming for with Olympus (in fact, that's 
what got me started with color-blindness simulation; I wanted to apply 
said simulation to Olympus). It would be ideal I think to get comments 
from someone that actually is a dichromat, otherwise I'm rather guessing.

Right. So, got anyone that can comment on [1]? Also, the Zion schemes 
can be seen at [2] ([3] and [4], specifically). Again, ignore the 
progress bar, those colors are known to be screwed up :-). Oxygen also 
is not the best style for maintaining a very dark background; Zion 
Reversed would be much more "black" in a different style.
