There is a basic test that you take and it determines what color you are. Either a white, yellow, red or blue. I was obviously a yellow and most of my close friends were too. We were carefree and were always looking for something fun. After doing this test and buying the book I took it everywhere that semester and gave the test to everyone to see what color they were and how we connected, etc....
So here is a little breakdown of each color.
WHITE - Peace makers. They are calm and balanced. They are generally kind and are good listeners.
YELLOW - Fun. Fun is what motivates them and they enjoy living in the moment.
RED - Power. They like to get things done and don't let others stop them. They are responsible leaders.
BLUE - Intimacy. These are the do-gooders that may be emotional and have quality relationships.
I took the test again recently and am still yellow, but not as much, maybe only 50% now. And I have adapted into other colors too. It said this about me:
"YELLOWS are motivated by Fun. They are inviting and embrace life as a party that they're hosting. They love playful interaction and can be extremely sociable. They are highly persuasive and seek instant gratification. yellows need to be adored and praised. While yellows are carefree, they are sensitive and highly alert to others' agendas to control them. yellows typically carry within themselves the gift of a good heart...."
Go HERE if you want to take the test (you have to give an email address to get the results) and see what you are, or you can always buy the book and get better descriptions of each attribute that is in correlation with your specific color. Try it out, you will not be disappointed.
