title: Customising the colours of vim's tab bar
body: <p>How would one go about modifying the colour of vim's tab bar?</p>
  
  <p>I have tried using</p>
  
  <pre><code>:hi TabLineFill ctermbg=N
  </code></pre>
  
  <p>which does change the colour of the tab bar's background to the colour that 'N' signifies, but this is all I have managed to glean from Googling. I had a look at <code>:help cterm-colors</code>, but I did not gain much more of an understanding from it.</p>
  
  <p>Would I be able to use this highlight facility to change the colour of an active tab's foreground and background, and an inactive tab's foreground and background? If so, how would I go about doing this?</p>
