Regardless of how ridiculous the colors are, I wouldn't go
around changing anyone's system settings.  That would be
cause for lynching a programmer or at least deleting the
program from the system.

The first thing you should do is make your application
adhere to the window system colors so it uses whatever a
user's settings are.  Unless you've also gone bonkers with
your program's colors, this is fairly easy (but tedious) to
do by using the system color code numbers instead of
selecting your colors from a palette.  These are the
negative color values you may have noticed as the default
background color of a form.  You can find a list of these
system color codes in Help, in AXP it's under  "ColorScheme"
in the Index.
