I have a pdf document (one sheet) which contains the background color
(white) and a 2nd color (writing, black). How can I replace one
specific color in the whole document (the writing color) by another?
I found how to change the color of contigous areas but that's not
what I want.
Have you tried "Select->by color" ? (there might be a tool in your
toolbox for that, depending on your gimp configuration, it looks like a
hand with one finger pointing on 3 colored rectangles).
You can set the threshold in the tool options window to refine your
selection borders. Then click on the writing to select all of it, and
drag and drop the new colour you want to the image window.
