\documentclass{minimal}
\usepackage{pstricks}
\definecolor{LBRed}{rgb}{0.9,0.1,0.2}
\definecolor{LBBlue}{rgb}{0.4,0.3,1.0}
\newcommand{\morerefadd}[1]{{\color{LBBlue}#1}}
\begin{document}
Sometimes I miss out\morerefadd{ }spaces from my text.  Sometimes I
even forget\morerefadd{ whole clauses}.
\end{document}

As I said, Philip's \relax idea fixes the problem.
