With this font (Latin Modern) yes. I noticed this too.

But try switching the font:

\documentclass{minimal}
\usepackage{fontspec}
\usepackage{color}
\pagestyle{empty}

\setmainfont{Charis SIL}

\begin{document}
\fontsize{100pt}{100pt}\selectfont
\noindent
^^^^00e4\\
a^^^^0308\\
a\textcolor{red}{^^^^0308}\"a
\hbox{U^^^^0308} U\textcolor{red}{^^^^0308}\"U

 ^^^^00c4\\
 A^^^^0308\\
 A\textcolor{red}{^^^^0308}

\end{document}


Now it *does* depend upon having the color commands.
