[NTG-context] lost colors (mkiv)

Hi, can anyone with an actual *luatex* test, if this fails (live ConTeXt is broken). My binaries are from the minimals at contextgarden (pragma tree), ConTeXt is the latest beta. \setupcolors[state=start] \starttext \newbox\TESTbox \setbox\TESTbox\hbox{Silence is sexy.} \hbox{{\color[red]Silence is sexy.}{\color[blue]Silence is sexy.}} \hbox{{\color[red]\copy\TESTbox}{\color[blue]\box\TESTbox}}% no colors with mkiv \stoptext Best wishes, Peter
