How to emulate git log --decorate's different colors per branch-type

In making my favorite git log view I've created this alias:

graph = log --pretty=format:'%Cgreen%ad%Creset %C(yellow)%h%Creset%C(yellow)%d%Creset %s %C(cyan)[%an]%Creset %Cgreen(%ar)%Creset' --date=short --graph

This creates an output like:

What I'm missing here is the different coloring of branch types like in log --oneline --decorate --graph.

The --decorate (which uses =short by default) gives the different recognized branches a different color. The branch types (HEAD, origin/master, origin/HEAD, master) are colored cyan, red, red, green. Mine however are uncolored; colored only with the yellow of the whole branches part.

Is there a way to give different colors to the different kind of branches with an own alias?

I don't believe this is possible. Looking through the git-log(1) man page, the only relevant format for --pretty seems to be %d, which gives you all the ref names. Since there aren't any options which distinguish the type of reference, you can't give each type a different color.
