How to change color of signature in Pro version?

[Toxicus Prime]

Hi, 

I use Adobe Acrobat Pro DC in my work, but I've also had to install Adobe Reader because I need to sign documents with handwritting signature in blue color, and with the Pro version I can't to change the color.

I've tried reinstall; uninstall and install again; do it in different computers, and isn't possible. In Pro version I don't see how to change de signature color.

Any idea?

I just got the latest update to DC Pro, and it now has a color change on it.
