There's a few links that I think might be able to help you:
 * Help:Signature
 * mw:Help:Signatures
 * w:c:rs:Help:Customising your signature

The first two links help with the more basic components of a signature, while the third link sort of helps with more advanced components, such as colour, font, etc.
