http://cdn.sstatic.net/wordpress/img/apple-touch-icon.png Currently Main Icon

With all the other sites (except electronics, which has the same icon for both), Meta has the B&W or sepia icon, while the main site's icon is coloured. This is also the case with the site's favicons.

With Electronics the icon is (same as the main site): http://cdn.sstatic.net/electronicsmeta/img/apple-touch-icon.png but it's favicon is(ie B&W): http://cdn.sstatic.net/electronicsmeta/img/favicon.ico
