[NTG-context] Chapter number in list colored (setuplist)

Hi, I want to color the chapter number in the table of content. The attribute "numbercolor" does not exist in setuplist. So I tried to color the chapter number via "numberstlye" ("numbercommand" is also not working): ---8<---------------------------- \define[1]\listChapterColor{\color[bordeaux]{X #1}} \setuplist[chapter][color=black,numberstyle=\listChapterColor] ----8<------------------------------ The X appears in the new color (bordeaux), but the chapter number is still uncolored - same color like rest of that line (black). What am I doing wrong here? H.
