Yes, that's it.  Previously I selected the whole sheet.  Then I
took a piece of the foreground only.

Thanks!

Dropping a color will fill the current selection. It doesn't matter at
all where you drop. Make sure that you select the right areas before
you fill.

That doesn't make sense, but if that's the problem, try inverting the
selection.  Problem solved.  It helps if the fill tool is used on the
black text, and if you zoom in (so that you can see individual pixels,
e.g. 800% zoom).  Then zoom out to see the whole document and see if
that works.

You may need to convert the pdf to rgb format and save it as e.g. an
XCF, but I doubt this will be necessary.  Are PDFs stored as indexed,
grayscale, or rgb?  I can't remember.

This only seems to work to change the color of the (white)
background.  It doesn't matter if I drop the color onto the
background or onto the black foreground.

I can't have missed the black color while dropping, because the pdf
also contains large black areas.

What can I do to select the foreground (color)?

Hi,

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.

TIA
Til


Hello,

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.


Regards,

Olivier.
