Thank you four your response. I tried this definition in my document  
(minimal example below).

like these warnings from my log?

** WARNING ** Interpreting special command push (color) failed.
** WARNING ** >> at page="1" position="(107.398, 759.621)" (in PDF)
** WARNING ** >> xxx "color push"

There is no color change at all in the output file.

I also get one more unexpected message when running this with my  
working file:

** WARNING ** You've mistakenly made a global color change within  
nested colors. <-- I cannot see how. It occurs apparently in this line:

\textarab[trans]{\newcolor{wa}-huwa} & \textarab[fullvoc]{\newcolor 
{wa-}huwa} & \textcolor{magenta}{und} er\\


Is it possible to investigate in what produces these warnings -- and  
prevents the color change???

Best, TH

--- example

\documentclass{minimal}

\usepackage{xltxtra}
\newfontfamily{\arabicfont}[Script=Arabic,Scale=1.7]{Scheherazade}
\usepackage{arabxetex}

\usepackage[xetex]{color}
\newcommand{\newcolor}[1]{\special{color push}\special{color cmyk 0 1  
0 0}#1\special{color pop}}%


\begin{document}

\textarab[fullvoc]{\newcolor{wa-}huwa}

\end{document}
