Styleguide is a plugin that allows you to edit Fonts and Colours in your WordPress themes.
I created this plugin to give my premium theme customers an easy method to edit the colours and fonts in the themes they had purchased.
The plugin has been developed in such a way that fonts can be edited in most themes. To use the colour editing the theme needs to add support for the functionality. I have added support for the default WordPress themes and will happily add support for other themes as well if anyone is interested.
