The gamma 1.0 shot looks just like I remember the NeXT (OK, it has 
been a few years, but I'm pretty sure), yet I do not have any gamma 
calibration turned on in my X server, and using test images it seems 
like my setup has a gamma of about 2.  Is it possible that the GNUstep 
system color settings were set by someone eyeballing things on a 
non-gamma-corrected system, instead of being numerically copied from a 
NeXT?

In any case, my "vote" is that whatever is done, it should be 
configurable from a GUI (the eventual Preferences app seems like a 
great place), even if it is a technical solution like gamma setting.  
(To make it intuitive, a slider could be used, and it could be called 
"Brightness (gamma)".)  GNUstep setup instructions should explicitly 
recommend the user run Preferences to fiddle with the colors.  Since 
this is the way you do things in Windows (adjust colors from a Control 
Panel item) and other environments this should not be something 
difficult or discomfiting for new users.

Perhaps holding off on this until there is time to develop the GUI 
might reduce the need for an unhappy compromise.
