You've defined it as a string when it needs a number for color.

#define FARBA_ZELENA 0x00FF00FF

Note that if you use FARBA_ZELENA for color embedding such as "This is a text "FARBA_ZELENA" blabla" then it'll give another error about find "-identifier" etc. In that case, rename to to another name and use it.
