I noticed that when run on a 256-color capable xterm, upon exiting the demo programs the colors in the bash shell are modified - e.g the bash prompt, the output of colored ls commands.
For instance, due to my fiddling with dircolors, a file with executable flags on is normally displayed in light green and it now appears in bright green, presumably #00ff00. CJ -- http://mail.python.org/mailman/listinfo/python-list
