Sometimes, I only want a single page, say, the titlepage or page 32, with colored background rather that the whole document. Here are some codes: \starttext% titlepage (yellow)
\startmakeup[standard]
\midaligned{How to make document}
\stopmakeup
% page1 (gray)
Many \CONTEXT\ users $\ldots$
\page
% page2 (darkyellow)
Many \TEX\ users $\ldots$ 
\stoptext
Of course, it is awful that if I set the titlepage yellow, page1 gray and page2 darkyellow. How can I achieve this? regrads, Tim
