colorcollect:

Howdy! This app …

• can collect CSS files from a website and extract the colors that are used in them.
• understands <base>, <link>, <style> and @import.
• so far only understands notations like #a6a366 or #f66.
• is limited to HTTP and HTTPS and cannot extract it's own CSS (due to Google Appengine restrictions).
• is very young and might fail at some websites. If it does, it will try to do so in a graceful manner. It might fail at that, too.
• wants you to help me by reporting errors or non-working websites to mail@saturnpolly.net.
• requires Javascript and so far has only been tested in Firefox 3.5, Safari 4 and Opera (looking a bit weird in the latter).
• wants you to stop reading and … start using it!
