Aditya, I want to know both please. Now I use the \start \definecolor ... ... \startmakeup[standard] ... \stopmakeup \stopto assign a specific color to the tilepage whose content is on a single page exactly. But I don't know how to set the background for a single page, say, page 3 if a document has more than three pages. Also, I don't know how to cycle pages through a finite list of colors. Can you show me that? Tim
One way to do this is to set \setupbackgrounds[page][background=color, backgroundcolor=\PageColor] and define \PageColor such that it expands to an appropriate color. For arbitrary control, you can use a lua function, for example: \startluacode thirddata = thirddata or {} function thirddata.getpagecolor(num) -- A lua function that assigns colors based on page numbers if num == 3 then context("blue") elseif num == 5 then context("red") end end \stopluacode \def\PageColor% {\ctxlua{thirddata.getpagecolor(\rawcountervalue[userpage])}} \setupbackgrounds[page][background=color, backgroundcolor=\PageColor] \setuppapersize[S3] \starttext \dorecurse{10}{\input knuth \par} \stoptext You can also use a lua table to assign colors, and then you do not have to build a ladder of if statements.
