[NTG-context] Combining "outer" effect with filled glyphs

Hi, I would like to get red text with black outlines. The magic in ConTeXt that does the outline is \starteffect[outer] Something \stopeffect but I would like to combine normal filled glyphs with an outline. While I'm able to come up with some magic to do this for single lines (creating zero width hboxes etc.), I would really like to typeset a complete paragraph on a poster. Is there any magic that would allow me to do that? Thank you, Mojca
