Black framing urls in pdf (and not blue)?

For an aesthetic matter I would like the coloring of the urls that appear in the pdf not to be blue but black, as well as the text. In the compilation formats there is an option to not color the links but apparently nothing seems to change.

If you’re referring to how external hyperlinks work (as opposed to internal cross-reference links), then the setting you’re looking for is in the Transformations compile option pane.
