Color in git-log

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"
