[NTG-context] groupedcommand with color

Hi, due to \color[]{} now needs an argument, groupedcommand doesn't work as before: \define\PlainSwitch% {\groupedcommand{\language[de]\ss}{}} \define\ColorSwitch% {\groupedcommand{\language[de]\ss\color[darkred]}{}} \starttext English: \date {\PlainSwitch German \date} English: \date {\ColorSwitch German \date} Test \date \stoptext Someone knows what to change here (in order to get the red "G" back)? Thanks, Steffen
