Hi Hans, Something has changed recently with the mkii color model, due to which page backgrounds do not change. (I am guessing that this is a grouping issue, but then colors are like a black box to me). Consider the following example \setuppapersize[S6][S6] \setupcolors[state=start] \definecolor [simpleslidestextcolor][s=0] \setupcolors[textcolor=simpleslidestextcolor] \startuseMPgraphic{simpleslides:MP:horizontal} StartPage ; fill Page withcolor 0.5white ; StopPage ; \stopuseMPgraphic \defineoverlay [simpleslides:background:title] [\useMPgraphic{simpleslides:MP:horizontal}] \starttext test \page \setupbackgrounds[page][background={simpleslides:background:title}] test again \stoptext In MKII, the background of the second page does not change. This used to work until a few months ago (around Dec, 2008) but stopped working after that. (It does not work in the Jan 18 version that I have). In MKIV, this works fine. Aditya
