[NTG-context] Set background color for a single page
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

See: http://thread.gmane.org/gmane.comp.tex.context/75726/focus=75743
Another alternative is to pick the color from a list using
\convertnumber{colors}{userpage}, similar to the solution at

Re: [NTG-context] Set background color for a single page
Aditya, Thanks. Defining a color conversion is a good idea, and we can apply
this conversion easily to somethings like chapter, section, etc. which has a
`color' filed to assign, but not pages. Is there a way to set the color of a
page like that done for chapters and sections? Tim

Re: [NTG-context] Set background color for a single page
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?

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.

Re: [NTG-context] Set background color for a single page
Aditya, thanks. I like this Lua way, but I have to explore the Lua world first.
Ok, reading PIL and coding in Lua.
