How to distance a menu from the last item

Hi there.
I would like to put the menu "Theme color" on the right in the main menu far from the last item. Is it possible?
so, I would like to distance a menu from the last item in the "main menu". How could I do that?

Sorry thats not possible! Each menu item must have the same padding/margin setup

If it is not possible that, is it possible to color that in different way?
How can I set up the menu "theme color" in a different color?

Therefore you have to add a css class to the Joomla menu item and then create a css for the menu item within your css/custom.css
