chapter title on a single empty page with background

[Mojca Miklavec]

Hello,

for some reason I have always been using standardmakeup for separating
chapters in slides (I don't know if that's a good idea or not), but
this fails:

\setupcolors
	[state=start]
\setuphead
	[chapter]
	[page=yes,
	 number=no,
	 command=\mychaptercommand]
\setuphead
	[section]
	[page=yes,
	 number=no]
\def\mychaptercommand#1#2{%
	\bgroup
	\startstandardmakeup
	\setupbackgrounds[page][background=color,backgroundcolor=blue] % doesn't work
	\switchtobodyfont[30pt]{#2}
	\stopstandardmakeup
	\egroup}

\starttext
\chapter{Chapter}

\section{Section} % starts on the first page
\input tufte
\stoptext

I have now used

\def\mychapter#1#2{%
% the only way to make background color work
\page\bgroup
\setupbackgrounds[page][background=color,backgroundcolor=blue]
\startstandardmakeup
\switchtobodyfont[30pt]{#1: #2}
\stopstandardmakeup
\egroup}

as a workaround, but I wonder: is my first attempt something that's
simply forbidden to use or did I use it in a wrong way?

Thanks,
    Mojca

just keep in mind that makeups are just vboxes, and that the chapter 
commands does quite some things,

page=,before=\startstandardmakeup,after=\stopstandardmakeup

may be a safer way
