How about \setupbodyfont[ams]
$\Bbb C$ ?
Note that it is also possible to use non-italic bold letters for this purpose.
In my files I've defined these commands, so I can change the layout, if I want.
\def\expe{{\rm e}} % Exponential e (upright)
\def\dD{{\rm d}} % Differential d (upright)
\def\iI{{\rm i}} % Euler's imaginary i (upright)
% set of numbers; format: IR, IN etc.
\def\bfN{{\Bbb N}}
\def\bfZ{{\Bbb Z}}
\def\bfQ{{\Bbb Q}}
\def\bfR{{\Bbb R}}
\def\bfC{{\Bbb C}}
% Alternative: bold and non-italic
%\def\bfN{{\bf N}}
%\def\bfZ{{\bf Z}}
%\def\bfQ{{\bf Q}}
%\def\bfR{{\bf R}}
%\def\bfC{{\bf C}}

For a fracture like I and R try \Re and \Im (defined in plain TeX). Or you can
redefine it as {\rm Im\>} and {\rm Re\>} if you want to get Re z and Im z
instead.
