I'm working on a settop device that has a 256 color screen overlay of 
the video, running X and GTK. One of the colors (rgb:80/00/80) is the 
transparency color that shows the underlying video. Old style X programs 
(such as xterm and icewm) can take an rgb triplet which makes it easy to 
make them transparent in this context. However, the gtk based programs 
I've tried (notably xchat) want a set of 16 bit values for color, and 
try as hard as I might I haven't been able to convince them to map this 
color properly.(e.g 32768/0/32768 and variants thereof do not map to 
80/00/80....

Is there a way to force a gtk based app to use a specific rgb 
triplet/change the visual/do whatever, to ensure a certain color is 
exactly the color I need for the transparent color?
