How to eliminate "ls" color in xterm -

[Bob Goodwin <bobgoodwin@xxxxxxx>]

How can I eliminate color in "ls" listings?

In .bashrc  can add    alias ls='ls --color=never'

But this does not change the listing in the gui terminal window.

There must be a place to "alias" ls  for something like    ls -l --si 
--color=never  ?

Thanks.
