Red signifies blood, which, in turn represents living, breathing souls. Yes, you can sign in red, if you choose to do so, however, purple represents royalty and you are a king or queen created in the image of the Most High, taking dominion over your status and standing. We recommend Witnesses signing in red, and you signing in purple. Just don't use black or blue ink for any signatures or autographs. Also, as mentioned earlier, use a 'red' ink stamp pad for your 'thumbprint seal.' Some people have even claimed to use saliva, or hair strands for DNA reasons, but that's not necessary because your thumbprint is like a snowflake, no two prints are alike in the whole world. Yours is strictly unique to you and you only. A thumbprint, along with two witnesses and a current photo is more than enough for your Patent of Nativity document. Even if the Witnesses have recorded their own documents and are Kings and Queens of their own domain, they still sign in red on your document as your Witnesses. You, the main document applicant, the name at the top of the document, and who the document is designed for, should sign in purple ink.
