Color Field is simple field that use a hexadecimal notation (HEX) for the combination of Red, Green, and Blue color values (RGB). Opacity is also support and can be disabled/enabled per field instance.
adds a formatter to the link field that adds the host favicon to the front of the link. It adds the favicon while still allowing you to choose, from the other formats, the format of the actual link.
Features
The module currently has 3 different ways of grabbing the favicons.
Google shared service
Getfavicon.appspot
Builtin PHP scraper with local caching.
The first 2 are web services while the built in scrapper is as the name suggests, a local PHP function that retrieves the favicon, stores it locally and keeps the file in it's original format which should not be a problem with modern browsers (as opposed to the web services that seem to convert to .png). The upside of this is that if the original favicon is animated, the animation is retained.
The builtin scraper is the default and seems to detect the favicons the best.
A use case of this module might be if users of your site are able to add links to their profiles on other sites, adding the favicon in front of each link makes each links destination more obvious.
