The colored text shows you who is talking. Notice the characters it introduces and text boxes both have colors. On page 1 it is the person of that choice talking to you in the colored box, since the color of the box matches the color around the image.
On page 2, the people it introduces you to on that page comment on the other choices. So for The Owl comment 1 (black) is from the government guy, comment 2 (blue) the devourer that wants to eat all, etc. These people will continue to comment on the choices in future pages.
On page 3 and beyond the first comment will often, but not always, be from the person in that choice speaking to you. The rest will be from the page 2 people as usual.
