Font Color options and setting required colors for Signature

We have certain documents that are REQUIRED to be signed in blue. Currently there is no way for senders to set this as a setting on the signature field. We are reliant on the signers remembering to upload a blue signature to their account (if they have one) and then also burden them  with remembering to choose it when signing these specific forms. 

Business Impact: High volume of incorrectly signed documents and frustration for our business teams

Solution(s): 1. Provide the ability for senders to set the font color on signature fields like we can with others. 2. Make adopting an alternate color signature available in the web signing session.
