title: Eclipse: change vertical bar color
body: <p>trying to deal with a minor issue here: I want to make my eclipse as distraction free as possible. So far I'm satisfied, except for one thing that I've not been able to figure out how to change:</p>

  <p>the white vertical bars are ... annoying. How can I change their color? </p>
  
  <p>Please note that the left ruler is not the code folding bar (which is on the right side of the line numbers), but the so called "vertical ruler" which shows line annotations (eg errors and stuff), to be found in Preferences > General > Editors > Text Editors > Annotations. This bar can not be deactivated (which I don"t want because i find it useful), I just want its color changed. Don't know what the right ruler is though.</p>

  <p>edit: but indeed a (partial) duplicate of <a href="https://stackoverflow.com/questions/204548/change-overview-ruler-color-in-eclipse?rq=1">Change overview ruler color in Eclipse</a>. Problem not solved: changing the system theme (mine is mediterranean dark) did not change the color of the bar.</p>
  
  <p>Thank you</p>
