Thanks to several people that responded to my question about blackbox decorations looking odd when I set my Macintosh to "thousands" of colors, especially Jeff Raven and Bradley Hughes. As they suggested, I used xdpyinfo to find out what color depths X is running at. Here are the results: Macintosh color depth | X depth | how blackbox decorations look 256 colors | 8 planes | degraded but usable; all controls visible; just what I would expect thousands of colors | 15 planes | degraded, unusable; many controls invisible in some styles; no gradients millions of colors | 24 planes | beautiful; gradients look great I seems odd that one of X's color depths is 15 planes rather than 16 (as in the example Jeff Raven sent me). Could this indicate a misconfiguration of X? But why doesn't blackbox degrade gracefully with 15 planes? David
