Thanks! That works. I'll dare to ask one more question. How to use 
colors in (some kind of) groups, meaning localy? In example, how to set 
some nice color for given object only (word, letter or rule)? Or should 
I always say something like

\pdfliteral{0 1 0 0 k}
  colorized text
\pdfliteral{0 0 0 1 k} % come back to black

Any clues?
