Hi Kathy and welcome to our community
Within RoboHelp HTML, creating a Font Set is pretty
straightforward. You will probably spend infinitely less time
creating a new font set than you would trying to figure out how to
go about importing the one you have. To declare the Font Set, make
sure a topic has focus and click Format > Font Sets...
I could be mistaken, but I think the custom color definitions
aren't stored globally. Again, I could be wrong about that. Where
are you referring to needing to see these?
Cheers... Rick
