title: Why don't most vim color schemes look as nice as the screenshot when I use them?
body: <p>I have downloaded many vim color schemas and tried them out, but many of them don't look like the official screenshot.</p>
  
  <p>For example, vim's own color schema - <code>desert</code> should look like this:
  <img src="https://i.stack.imgur.com/1fFmd.png" alt="desert color schema"> </p>
  
  <p>But in my vim, many colors won't display, for example the background.
  <img src="https://i.stack.imgur.com/TVBIg.png" alt="my vim color display"></p>
  
  <p>But some color schemas work correctly.</p>
  
  <p>Why is that?</p>
  
  <p>In the:
  Edit-> Profile Preferences -> Colors, I select the "use colors from system theme"</p>
