And that is a perfectly legitimate interpretation. It just seems to me that the blue associated with his person/gift/speechbubbles but literally nowhere else on the page, not even as part of any green or purple, seems a little bit overly pointed in this scene. It might have been more subtle, but still open to the view that he believed himself predestined, if the gift was a little further from the shade of the speechbubble, and some of the shirt stripes were a different color (perhaps if the lighter stripes were white?). Sorry I wasn't more precise the first time around.
