Git ships with `diff-highlight` which is more than enough for me.

I use the following config.

    [core]
      pager = /usr/share/git-core/contrib/diff-highlight | less

    [color "diff-highlight"]
      oldNormal = red
      oldHighlight = 16 bold red
      newNormal = green
      newHighlight = 16 bold green
