I can clearly see a difference on both my CRT and my laptop display and
to be honest I have to say that if I ask KDE to lighten the red and I
get something that is in the lower third of the left bar then thats
somehow wrong - IMHO. The right bar seems to work better wrt to lighten
or darken a given color.

As far as the question wether this is needed for KDE 4.0 I don't know,
the question is: Can this be added after 4.0 within the SIC and BIC
limits that we have?
