I have achieved this by the following method:

 I think we'd better only change the label by \setupheadtext and chage its style by \setuphead. An example as follows
 
\setupheadtext[content={CONTENTS}]
\def\mytitle#1{%
  \midaligned{#1}}
\setuphead
  [title]
  [style={\bfb},
   color=red,
   before={},
   after={\blank[3*big]},
   textcommand={\mytitle}]
 
it works well for me :-)
 
but please note that if you use \title in the frontmatter, the title also will be changed. Maybe you want to define your own title to solve this problem.
