Dear list, One more (last) problem regarding layout I can't resolve by myself: I've got a little booklet (2 A5 pages on one A4 sheet). The outside margins are colored in blue. I would like to color the left outside margin in yellow and keep the right outside margin in blue. I've read and tried to adapt the 'Alternative backgrounds' example on the wiki without any success. When I try to use leftpage (or rightpage) in \setupbackgrounds, the background of the whole left page is colored. Here is what I have right now: Thanks a lot for your reply, -AJ \definepapersize[pca4][width=212mm,height=299mm] \definepapersize[pca5][width=149.5mm, height=212mm] \setuppapersize[pca5][pca4] \setuparranging[2UP,rotated] \setuppagenumbering [alternative=doublesided] \definelayout [default] [leftmargin=0mm,rightmargin=25.5mm, topspace=0mm,backspace=10mm, width=115mm,height=middle] \setuplayout[location=middle] \setuplayout[default] \setupbodyfont[sansserif,10pt] \enableregime[utf] \setupcolors[state=start] \setupbackgrounds [text,header,footer] % with leftpage here, doesn't work [rightmargin] [background=color,backgroundcolor=blue] \starttext Hop \page[yes] foo \page[yes] bar \stoptext
