Greentext is a simple plugin that enables >greentexting in comments, posts, and pages.
Greentexting, originally from imageboards, is a convenient way to quote, summarize, or tell stories.
The plugin gives any line that starts with the > character (or its HTML entity) a default style of color:green, but you can reference the span class greentext in your CSS to style the greentext however you want. For example: span.greentext{color:blue;font-weight:bold;}
