Red is such an interesting color to correlate with emotion, because it's on both ends of the spectrum. On one end you have happiness, falling in love, infatuation with someone, passion, all that. On the other end, you've got obsession, jealousy, danger, fear, anger and frustration.
When I'm getting to know someone, I look for someone who has passions that I respect, like his career. Someone who loves what he does is really attractive.
