Here is a example where I used a few helpers, e.g. \installdirectcommandhandler
creates \setupreferencecommand and \referencecommandparameter.
\unprotect
\installnamespace {referencecommand}
\installdirectcommandhandler \????referencecommand {referencecommand}
\def\referencecommand
{\dodoubleempty\referencecommand_direct}
\def\referencecommand_direct[#1][#2]%
{\begingroup
\ifsecondargument
\setupreferencecommand[#1]%
\edef\m_reference{#2}%
\else
\edef\m_reference{#1}%
\fi
\usereferencecommandstyleandcolor\c!style\c!color
\getreference[title][\m_reference]%
\doif{\referencecommandparameter\c!label}\v!yes{\referencetext\v!page}%
\referencecommandparameter\c!left
\getreference [page][\m_reference]%
\referencecommandparameter\c!right
\endgroup}
\definelabelclass[reference]
\setupreferencetext[\s!en][page={ on page }]
\setupreferencetext[\s!de][page={ auf Seite }]
\setupreferencecommand
[\c!label=\v!yes,
\c!left=(,
\c!right=)]
\protect
\starttext
\dontleavehmode\reference[knuth]{Donald E. Knuth}%
\input knuth
\blank
\referencecommand[knuth]
\blank
\referencecommand[left={[},right={]}][knuth]
\blank
\referencecommand[style=italic,color=red][knuth]
\stoptext
