background color doubleclick

[Andreas Höschler]

Hi all,

doubleclicking on text in an NSTextField highlights the selection. On 
my Sun Ray screen the color (some light blue) has a nice contrast and 
is easy to see. On a NEC monitor this color is much brighter and thus 
hard to see. I assume this can be controlled (selected) with a

        defaults write NSGlobalDomain ...

command but what will be the key and the possible values for that?

Thanks a lot,

 Andreas
