The problem is that color directives are postscript directives. They are
interpeted by the postscript interpeter (gs, or the printer).

Originally you have:

  \textcolor{cyan}{some ltr text}

Which will be translated to:

  [postscript:make color cyan]some LTR text[postscript:make color black]

However, with rlbabel the order of text is reversed. Suppose you have:

  \textcolor{cyan}{\hebalef\hebbet}

This whole paragraph is in right-toi-left mode, so tex here simply
reverses everything:

  [postscript:make color black]{bet}{alef}[postscript:make color cyan]

Whereas you really need:

  [postscript:make color cyan]{bet}{alef}[postscript:make color black]


One way around this is to wrap \textcolor with a macro that adds \L and \R

  \newcommand{\textcolorR}[2]{\L{\textcolor{#1}{\R{#2}}}
