Lyric discussion by MindsTheatrre 

I don't think there is a relationship in this song, at least not in the official sense. Fiona's careful with her words. If she's seeing red, then they aren't together - they're getting bright. So why can't they be together? A hint might be in the colors, and her subsequent frustration. He's a coward. She can't reach him (like the diamond) and doesn't understand why. So the concern isn't the disconnect - it's the doubt. She honestly doesn't know if his resistance is because of his fear or her acts.

Everything is a juxtaposition: the colors, the diamonds (bright) compared to the mining (dirt, dull), and truth/lies at the end. Musically, the song's center is neither major or minor. The entire doubt is then internalized to the song. Wonderful.
