I think that I have found an answer: in the \setupinteraction command that
manages URL's, hyperlinks, PDF properties, etc. include
color=,contrastcolor=,
\usemodule[letter]

\useURL[recipient-email][mailto:addres...@gmail.com][][addres...@gmail.com]
%% Would like this URL to match the color of the main body

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
