Template:Signatures/The last username left

This page is my advanced signature. It includes my base signature with a random color chosen by my random color chooser page. It also passes along the given time, if specified. Unfortunately, the task of creating a signature with varying colors that still passed along the time was not possible with a single page, so I created the other required pages as sub-pages of my userpage.

Here are the requirements for the signature. If anyone can figure out a way to do all this in a single page, please tell me on my talk page (link inside signature).
 * Optionally take a time argument, and display it if given.
 * Optionally take a color argument. If given, use that color, otherwise pick a random color.
