Tmux TrueColor (a.k.a. 24-bit color) Support

Prerequisites

Unfortunately, homebrew does not support --with-universal-ctags option for global (on the state of April 2018) The reason is that universal-ctags is not officially released yet.

Install universal ctags

Run brew install --HEAD universal-ctags/universal-ctags/universal-ctags (See https://github.com/universal-ctags/homebrew-universal-ctags repo)

If you're on macOS, you might have an old ctags installed with command line tools for XCode. To fix this, simply run alias ctags="brew --prefix/bin/ctags"

  margin: auto;
}

The Fast Blazing Solution

Instead of tmux-256color, use screen-256color which comes with system. Place this command into ~/.tmux.conf or ~/.config/tmux/tmux.conf(for version 3.1 and later):
