title: PhpStorm How to change suggested colors when editing CSS files
body: <p>When editing the CSS file in PhpStorm (2016.2) it opens up the color suggestion box every time I add a line with al color, border, background-color and so on. The suggestion box seems to have lots of possible colors to select from.
  How to limit that selection to only just those few that I already use in the project? Otherwise this suggestion box is useless suggesting hundreds of other colors.</p>
