Can you do this with iText? Yes. HOWEVER it is going to require you to have a
VERY DEEP understanding of PDF and Color Management/Science.

Subject: [iText-questions] Changing colors of graphics and text in imported PDFs
Hi,
I'm trying to find a way to manipulate the colors in existing PDFs. I saw some
similar questions asked 6 or more years ago and I'm not sure if things have
changed.
Imagine I have a design that started in Adobe Illustrator with text and
graphics and there are 5 distinct colors used in the design such as a color
palette like ones you see on https://kuler.adobe.com/. The goal is to be able
to identify the 5 colors in the PDF and replace with with entirely new CMYK
colors as if I can just change the palette of the design on the fly from code.
If it helps, I could make all 5 of the initial colors anything such as a named
spot color.
Can I (or do I want to) do this with iText?
If not, what about string manipulation / search and replace?
Or I see in past posts there was some mention of other programs to do this but
some examples would be helpful is iText isn't the right tool for this purpose.
Thanks!
