Default Themes

Permalink
I was recently working on a website for a client and there were a lot of distractions and I was not fully paying attention to what I was doing and deleted one of the 4 default themes. Out of all the themes I have seen it was the only one I really care for and I would like to get it back and get to restoring that theme to how I had it.
In short I am trying to figure out what the themes are that come with the C5 install.
I have;
Plain Yogurt
Green Salad
Dark Chocolate

What is the 4th one?
