I find that interesting. I can definitely relate to Red the most.
Here is something that I also find interesting. It's a personality test that tells you what your color is.

Apparently my color is Red according to the test I linked above.
Congratulations, You are a Red
Motive [ Power ]
reds are motivated by Power. They seek productivity and need to look good to others. Simply stated, reds want their own way. They like to be in the driver's seat and willingly pay the price to be in a leadership role. reds value whatever gets them ahead in life, whether it be in their careers, school endeavors, or personal life. What reds value, they get done. They are often workaholics. They will, however, resist doing anything that doesn't interest them.
ABOUT RED
Reds like to be right. They value approval from others for their intelligence and practical approach to life, and want to be respected for it. Reds are confident, proactive, and visionary; and but can also be arrogant, selfish, and insensitive. When you deal with a RED, be precise, factual, direct, AND show no fear!
Seems I'm blue. I guess.
Motive [ Intimacy ]
Blues are motivated by Intimacy. They seek to genuinely connect with others, and need to be understood and appreciated. Everything they do is quality-based. They are loyal friends, employers, and employees. Whatever or whomever they commit to is their sole (and soul) focus. They love to serve and give of themselves freely in order to nurture others' lives.
ABOUT BLUE
Blues have distinct preferences and have the most controlling personality. Their personal code of ethics is remarkably strong and they expect others to live honest, committed lives as well. They enjoy sharing meaningful moments in conversation as well as paying close attention to special life events (e.g. birthdays and anniversaries). Blues are dependable, thoughtful, and analytical; but can also be self-righteous, worry-prone, and moody. They are "sainted pit-bulls" who never let go of something or someone once they are committed. When you deal with a BLUE, be sincere and make a genuine effort to understand and appreciate them.
Nurturing others lives? Hardly worth the effort unless something down the road makes it worth bothering. The description from the first link seems a little more... all-inclusive for traits, probably because it's not trying to make a quick buck.
