How to export paragraph styles in Pages?

Here for example are four Paragraph Styles I often use: Notice I have them all set up nicely, even with the F-key. My remote colleague was working on a similar document. I wanted to say to her "Here, please take these, and use them it will be easier". Similarly I often want to "take" those from my document, and "add them to" another document I have before me. How is it done?
