maybe you should copy the verb-JV file and take that one as a starting 
point since it has a different / handler,

the following kind of demos what you should do; make sure you use the 
proper namespace

\gdef\PLtypeWHATEVER#1%
   {\endPLtypesix
    \xdef\PLprefix{\getpretty{#1}}%
    \ifinPLcomment
      \getpretty{#1}%
    \else\ifinPLsingle
      \getpretty{#1}%
    \else\ifinPLdouble
      \getprettydata{#1}%
      \ifnum\prettytype=21
        \beginofpretty[\!!prettytwo]\getpretty{#1}\endofpretty
      \else
        \getpretty{#1}%
      \fi
    \else
     %\beginofpretty[\!!prettytwo]    % THIS IS WHERE THE COLOR IS SET THAT 
YOU DONT WANT
      \getpretty{#1}%
     %\endofpretty
    \fi\fi\fi}

\gdef\doPLtypefourtwo#1#2%
   {\PLverbosefalse
    \getprettydata{#2}%
    \ifnum\prettytype=62
      \expandafter\PLtypeWHATEVER
    \else
      \expandafter\PLtypefourone
    \fi
    {#1}#2}

part of the complication has to do with the fact that keywords are parser
