Background colors in the status line (and elsewhere in vim) are not displaying. This may be because I am using someone else's Lightline config, but it looks quite different to what I am seeing.

no bg colors

My init.vim file:

  • macOS terminal doesn't support termguicolors

As stated by D. Ben Knoble, Terminal.app does not support termguicolors. I have found that using iTerm2 I can have these display perfectly.

  • For completeness, here is a list of terminal applications. Alacritty and Kitty are two other popular macOS ones in addition to iTerm 2. Mar 4 at 21:38
  • I meant to say “terminal applications that support true colours” Mar 5 at 1:49
