GreenIcon wordpress theme
3 Column theme with green header, black sidebars and silver post areas. Page menu has nifty icons and theme works with 2.3.1 and below.
This template is almost purely CSS based so is a perfect example of how you can modify your sites look and feel just by manipulating your stylesheets. It is very low bandwidth with minimal graphics used in this WordPress theme.
The Primary colors that are utilised are green, black and gray. There are dynamic icons utilised for the display of the dates on your article posts.
The only other graphics in this theme are in the clearly visible top header bar that is in black under the green header. The icons in the navigation bar include a custom home icon, an RSS feed icon and custom icons for the other pages that you deem important enough to include links to your main navigation area.
