[Download] SharePoint Color Palette Tool

Hello, I am the Installation Software License Manager for Joint Base San Antonio.  I have a question about the SharePoint Color Palette Tool.  We have a request to approve the installation of 9 copies of SharePoint Designer 2013, which is no problem because it is certified for use on the Air Force networks.  However, they also want to install the SharePoint Color Palette Tool with it.  I cannot find a certification for that Tool on any of our approved software lists.  I was wondering if it is possibly nothing but a plug-in which would not even work as a standalone software product without SharePoint being installed or what?

Thank you in advance,

Thomas
