I know you cannot utilize Pantone colors directly within ArcMap. I am curious if that is something that has been added to ArcGIS Pro (not seeing it, but might just be missing it), or is in the plans to do so. Any information along these lines would be much appreciated!
no mention in help at all... lots of web chatter, with a basic no, unless you want to spend the time to match pantone colours to cmyk manually
Pantone color support was added for the 2.7 release of ArcGIS Pro. There are 8 styles of Pantone colors each corresponding to a Pantone color book.
