How to set RGB palette as default for ALL drop down palette options

I currently have my default palette set to RGB when I start a new document, as my default palette in my drawing desktop, etc.  However, when I get to certain palette drop downs, it still defaults to Pantone colors.  How do I correct this to have all palette options (drop downs, etc.) default to RGB?  In the image below I am changing the color of all the lines in a table.  It happens in other instances, too--such as changing the color of an outline within the Outline Pen box.

I appreciate any help!
