Changing channel colors with lua?

[DaBear78]

Just a short question: Is it possible to change the color of a channel with a plugin? I'm asking because in the german/french client the colors of the chat will be saved in the layout file (/ui layout save), but they won't load (/ui layout load). So my idea is a small plugin where you can save your current settings and transfer them to your other toons (by loading / running the plugin with your alternate toons). Is this possible?
