When you look at the UBB code, you can see the poster applied different color to that section, either intentionally or accidentally:

Correct.
When a poster alters the text color, it can occasionally cause readability issues, depending upon user settings, default settings, etc.
If you can't read it well, then "highlight" the text with your cursor and it will change in the temporary capture, probably allowing you to read it.
