Hi, I do a small test with 2 columns and textbackground : ------------------------------------------------------------------------------------ \setupcolors[state=start] \definetextbackground[preface] [backgroundcolor=green, backgroundoffset=.25cm, offset=.5cm, frame=off, location=paragraph, color=blue] \starttext \chapter{Chapter TEST} \startcolumns[rule=off,n=2] \starttextbackground[preface] \section{tufte.tex} \input tufte \section{knuth.tex} \input knuth \stoptextbackground \stopcolumns \stoptext ----------------------------------------------------------------------------- The result is very strange : http://people.vnoss.org/~vnpenguin/pub/context/test-bgcolor.png http://people.vnoss.org/~vnpenguin/pub/context/test-bgcolor.pdf I'm wrong some things ? Thank you, Q.
