hmmm ... I hadn't noticed that before. Now that you mention it, though, I see that a few of the four-star decorations have red text.
 * Train Spotter
 * Diesel
 * Wisdom Seeker
 * Gift Giver
 * maybe more

I have no idea why these decorations have different color text. That sounds like a question for Pixel. :-)
