ls colored output does not work with Emacs backup files, #*#

[Philip Ganchev]

The program "ls" cannot be configured to use a special color when
listing backup files that start with a hash character (#).   A
commonly encountered example of such files is backup files produced by
Emacs: their names match the glob pattern #*#.

"ls" can be made more usable if backup files could be listed in an
understated color (such as grey), because the user usually is not
interested in seeing their names when s/he executes "ls".  This
currently works with Vi's backup files (*~).
