well, we have already
state=repeat: same background each upcoming page
state=start : enable background (calculate each time)
state=stop : disable backgrond
so we would have
state=once : enable background and after this page disable it
in this case 'once' is kind of start before and stop after \page
a range makes not much sense as one seldom knows the page in advance so
that would then be named pages; however, as we have 25 page areas it
would involve more testing then i currently want to do (the otr is
already not that fast)

No we won't know the page numbers so forget mine.
There's just one other thing: since we are changing background colors,
we probably need the text colors to be changed as well. But by searching
the sources, I only get the negative color scheme which is some sort of
pdf specials or gs specials. I mean can we just customize such configurations
ourselves? Like colorscheme={inverse+0.1} will inverse the color and reduce
the RGB value to 10%. Then my little test file could make more useful.

This must have something to do with the OTR, I'm really not good

By \definecolor[black][r=1, g=1, b=1] you can get white texts which

\chapter{hello}
\dorecurse{10}{\input zapf } % all the characters in the first page

Took me a while but with the help of the MkII/IV manual I was able to
implement the chapter layout.

Re: [NTG-context] two newbie questions (about conditional processing)
As you said before, in my problem, this kind of handler could break something
like hyper-links, and I assume Yue wanted those kind of stuffs.
Maybe just a \start(stop)setups which changes the background back to normal
and \prependtoks it to some token list. So is there an \everypage or
\everyshipout
token? Then using \setuphead (I don't know if it's appropriate) or
\appendtoks to
every title page.

[NTG-context] two newbie questions (about conditional processing)
Hi,
I have a new book to design, but I don't know how to do page/content
conditional processing). Please help me:)
- I want my chapter page (first page of each chapter) to be really
distinctive. that is, I define a dark color background, and want all
the text on the first page set in white. how can I do that? for
example
\chapter{hello}
\dorecurse{10}{\input zapf } % all the characters in the first page
should white, others should set in black.
- I want to insert graphics and images. all the graphics are inserted
using \placeexternalfigures. I want all the pages where the insertion
happens to be quite distictive (that is, have a very narrow text
layout, and leave the large margin for the figures. However, when a
page starts, TeX does not know wheter or not an external figure will
be placed on this page, so it really has no idea whether this page
should be set narrower or not. how can I do that?
Thanks.
Yue Wang
