I admit to being somewhat confused by your remark - I didn't change the screen while running vim or less. 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?
Interestingly, I find that I can keep pressing ENTER and 'clear' the screen back to how it was, but this is an ugly solution.
Kind regards,
Rob

vim (and less, since you seem to have the same problem there) use
something called an "alternate screen". This is a feature of the terminal
that allows the program to make arbitrary modifications to the terminal
screen that will be undone when the program switches back to the main
screen. In particular, any color changes will be undone. Consequently,
if you wish to change the color of the main screen, don't do this while
running vim or less.
HTH,
Igor
