OK, here is one. But now that SMiyata informs me that xdv files do not
contain directional informations, the result will certainly not be
different on Mac.

\documentclass{article}
\usepackage[dvipdfm]{color} % <= change to xetex driver when using xdv2pdf
\TeXXeTstate=1
\begin{document}
\everypar={\setbox0=\lastbox \beginR \box0 }

black black black black black black black black black black black black
black black black black black \color{blue} blue blue blue blue blue
blue blue blue blue blue blue blue blue blue blue blue blue
\end{document}

(same result as above when using pdftex driver with pdflatex)

For comparision, the following is for lambda + dvipdfmx :

\documentclass{article}
\usepackage[dvipdfm]{color}
\let\origshipout\shipout
\def\shipout#1{\origshipout#1 dir TLT}
\begin{document}
\pardir TRT\textdir TRT
black black black black black black black black black black black black
black black black black black \color{blue} blue blue blue blue blue
blue blue blue blue blue blue blue blue blue blue blue blue
\end{document}

Now the words are colored as they should: black is black and blue is
blue :-)
