Coloured git output on console is a very helpful feature. It was enabled by default on git interface cogito. I liked it, but had to switch to raw git few years ago (cogito is deprecated now).

[diff] color = true [pager] color = true [status] color = true
Additionally pager used (less in my case) should support ANSI colors (~/.bash_profile):
export LESS="-R"
And now diffs are rendered using colors that improve readability (anyone who doesn’t review changesets before commit? 
). Now diffs look much better on a X terminal:
