Hi Venkat, you're probably just running out of colours :-( try closing 
some other applications and trying again.

If you're using gtk1.2, you could try adding

   gdk_rgb_set_min_colors( 64 );

in your startup code. This changes the size of the cube that gdkrgb 
dithers to. Smaller values will use fewer colours, but look worse.
