Hi, I'm starting a presentation with ConTeXt.
I'd like to visually differentiate each section, so I've come up with
two complementary approaches to do that:
* Use a different color palette for each section, and
* Mark the progress bar to indicate the start of each section.
I've done an small example (at the end) but:
* Last Subject of a Topic take color from next Topic. (e.g. "Some
greenB")
* I don't like interactionBar styles provided.
I'd like something like:
|-----|-|-----|--|------
(horizontal line and a vertical line at the begin of each section and a
vertical line of different color for current position)
other option I like:
######%%@@@@@@HHH&&&&&&&
(each letter represents a color. It's a bar with colors marking size of
text. So it's a series of color rectangles with colors for each section
and a vertical line for current position)
The main problems are:
* How can I pass the first page of each section to MetaPost?
* How can I protect background color of SomeGreenB to be green and not
blue?
Thanks.

you need to get the logic ok yourself, something like:
\startuseMPgraphic{PageShape}
StartPage ;
numeric n ; n := \number\nofsubpages ;
numeric m ; m := \number\subpageno ;
if (n > 0) and (m > 0) :
pair pa ;
path p ; p := (100pt,100pt) -- (500pt,100pt) ;
draw p
withpen pencircle scaled 5pt
withcolor "BackgroundColor" ;
for i=0,n-1 :
pa := point(1/n) of p ;
draw (pa + (0,10pt)) -- (pa + (0,-10pt))
withpen pencircle scaled 5pt
withcolor "BackgroundColor" ;
endfor ;
draw point (1/m) of p
withpen pencircle scaled 10pt
withcolor "PositionColor" ;
fi ;
StopPage ;
\stopuseMPgraphic
> * How can I protect background color of SomeGreenB to be green and not

just look at the definitions you load ...
\definecolor [MyBackgroundColor] [s=.85]
\setupbackgrounds
[page]
[background=color,
backgroundcolor=MyBackgroundColor]
