Make mine Blue. I work as a paralegal and what many people do not realize is that you should always sign legal documents in BLUE ink. That way you will always know whether or not a document is the original as almost all photocopiers will copy the signature as BLACK. Because this is so deeply ingrained in me (I've worked in the legal profession for over 20 years) I always sign everything I do in BLUE ink - checks, contracts, notes, etc.
