[NTG-context] Change the default text colour for entire document

Hi, In ConTeXt to change the default text colour for the entire document, there are at least two settings that need to be configured: \setupcolors[textcolor=red] \setupinmargin[line=13,color=red,style=slanted,] The border colour for tables remains black: \setupcolors[textcolor=red] \setupinmargin[color=red] \starttext {\bTABLE \bTR \bTD One \eTD \bTD Two \eTD \eTR \eTABLE} \stoptext How can you override *all* instances of black? (Ideally there would be a single setting that is inherited by all.) That is, it is difficult to know all the various aspects of a ConTeXt document that use the default black colour -- margins, body text, table borders, and possibly more that I don't know about. Thank you!
