title: How to change the highlights for selected text and selection/word matches?
body: <h2>Visual confusion: 'selected text' and 'selection matches' highlight color</h2>
  
  <p>As a daily VS Code user I found an earlier closed issue (<a href="https://github.com/Microsoft/vscode/issues/1636" rel="noreferrer">Selection and selection matches highlight color #1636</a>) about this - i.e. if you <em>actually select</em> some text it's highlighted, but the highlight colour is all but indistinguishable from the highlight used for matched code or the same word.</p>
  
  <h2>A local user settings-like CSS override?</h2>
  
  <p>If the system-wide highlight colour (when selecting <em>any</em> text system-wide) isn't portable to VS Code, I need a way to edit it. Perhaps in the theme's CSS or - preferably - in a user-generated 'override css' file or something (like VS Code's user settings). Is this in the pipeline? If not, does anyone have a fix?</p>
  
  <p>ATM changing the highlight colour for selected text appears to be impossible. I'm using 'Dark', but the issue is the same no matter which theme.</p>
