I edited the properties of the console so that it would affect all consoles with the same name, changed the PS1 environment variable in my .bash_profile, closed the console, re-opened it, ran vim and/or less, exited vim and/or less and then found the console colors changed. Have I misunderstood your point?

That's strange.  My first action after creating the desktop icon to start
a local Cygwin console is to change the cursor shape ("large"), the font
(Lucida Console, 12pt) and the fore- and background colors (black on grey)
in the shortcut pointing to the cygwin.bat script.  I don't see what you
see, the colors are..., well, "stable".  The colors are only scrambled up
while still running in the console window in which I made the changes.
I have no idea what could be different in your setup, sorry.
