just go to the VIEW tab - Styles - Fae Styles and add a new one or change an existing.
And best I also would recommend, to go to the Style Organizer afterwards and copy the new styles/colors to the material database of Your choice.So You have them available for every future part.
"Styles" with the letter A's next to it......I thought it was for fonts...so I didn't look in there for colors to paint faces etc.
I think that file was created [quite some time ago now] by our good man Dave Merritt [@uk_dave].
I think you may be correct, sir. Thanks, Dave!
<edit> Actually I think there were two parts. One Pantone, one RAL and I combined them with SE defaults. I think.
