I would like to change the color of URL's in parts of a document.
In particular I am using the letter module and would like to have the color
of URL's match the color of text in the letterhead and then change to match
the color in the main body of the letter.
I can set the URL color once with \setupinteraction but I do not see how to
change it thereafter.
Thank you very much for your guidance.
Best,
Michael
