VI commens hard to read

I use vi to edit python files from a remote server.  Comments are shown in dark blue, with a very poor contrast with the black background.

We can change this behaviour setting the correct color:
:set background = dark

or We can change the entire color scheme, i.e. desert
:color desert

Both solutions are volatile when we close the file, so if we want to make it permanent, we need to write it in .vimrc file in our home directory.
