When you run git log --decorate --pretty=oneline the output will have entries like (HEAD, refs/published/master, master) with coloration.
I also have the following in my gitconfig:
[color "branch"]
current = yellow reverse
local = yellow
remote = green
How do you replicate those colors when doing a custom format like the following?
git log --decorate --stat --graph --pretty=format:"%d %Cgreen%h%Creset (%ar - %Cred%an%Creset), %s%n"
As of git 1.8.3 (May 24, 2013), you can use %C(auto) to decorate %d in the format string of git log.
From the release notes:
* "git log --format" specifier learned %C(auto) token that tells Git
to use color when interpolating %d (decoration), %h (short commit
object name), etc. for terminal output.)
