Not really a solution, but you could always save the material in a token
list register rather than a box.  Alternatively you might want to
consider using XeTeX, in which the solution is trivial :

% !TeX Program=XeTeX

\setbox 0 = \hbox {abcd}
\special {color push cmyk 0 1 1 0}
\copy 0
\special {color pop}
\special {color push cmyk 1 0 1 0}
\copy 0
\special {color pop}
\special {color push cmyk 1 1 0 0}
\copy 0
\special {color pop}
