I am struggling with the color of bibliographical references.

I found (Ulrike’s) hack to render the items in the bibliography the regular color (black):

There the problem seems to relate to the use of \setupinteraction.

Now, in my citations (\cite[Douma1979a]) the authornames are still colored.  Douma, 1979a, 86 

I examined the contextgarden site, read and tried the answers to previous questions, but could not find out how to do this.

Is there a way to control the author names?

Thank you in advance,

Kind regards,

Robert
