[NTG-context] followtokens & font color

Hi all, I use \followtokens and I would colorize the text. I've try some drawoptions or ConTeXt command to switch font color (i.e. {\red red text}) and nothing works. Is it possible to switch color during \definefont[RotFont][] ? Any idea on how to do this ? PS: Please, is there anyone who can answer to my thread [NTG-context] headers of multiple pages toc ? Thanks
