signature

The COLOR stuff gets ignored, at least when ecapsulates URL

Look at my signature.

You must be doing something wrong. The code Codingforums (http://codingforums.com)
would give the following output.

Thanks, was doing something wrong, but I would kind of expected that this would do the same:
1.
x.net (x.net) (color tag nested inside url tag)
2.
x.net (url nested inside color tag)

The second does not work.

Because the CSS of the forum overrides the link color.
