This is actually quite tricky. You’ll need to parse the page content stream and find all of the text drawing operators and then identify the strings which you’re interested in, split them into substrings and add the color changing operators for those specific words.

PDFStreamParser can do the content stream parsing but the rest is up to you I’m afraid.
