No. It's nothing to do with the LyX macro. The problem occurs when you color a
chapter heading (which is something you shouldn't do anyway, at least not
locally ;-)) in the specific constellation the Tutorial is using.
The problem is in the way the page headings are generated: The page headings
are upcased, and the color definition, which goes to the heading and the TOC
as well, is upcased in the headings, too. Thus the error message about the
unknown color "RED". In fact, only "red" (lowcase) is defined.
The document compiles if you put in the preamble:
\definecolor{RED}{rgb}{1,0,0}
