Blues are motivated by altruism.
Blues love to do nice things for others. They look for opportunities to give up something in order to bring another person happiness. Selflessness rather than selfishness is their guiding philosophy. Many Blues are uncomfortable doing things for themselves. They hold doors open for people, offer rides when someone's breaks down, contribute to charity, even devote their entire lives to helping others.
Blues crave intimacy.
More than anything else, Blues want to love and be loved. A Blue will sacrifice a successful career to improve an important relationship. Once considered a female characteristic, this nurturing is more accurately understood as a Blue personality trait.
Blues are gratified when they are listened to, when they feel understood and appreciated. They are notorious for revealing their inadequacies because they value being known and understood so much. In the eyes of a Blue, being vulnerable is small price to pay for the chance to be close. Blues may have their hearts broken more than most people, but they also spend much more time in love.
Blues need to be loved.
With Blues, a simple pat on the back will not suffice. Blues expend such great effort in making the world a better place that sometimes they need to be told how wonderful they are. They need to be thanked and specifically remembered for their good deeds. They need gratitude. They delight in being remembered on birthdays and other special days, especially if the remembrance is personal---a homemade anniversary card, a welcome home party, a special day that isn't on the calendar. Blues need tender loving care.
Blues are directed by a strong moral conscience.
Blues are motivated to behave in a proper, appropriate manner. They have a moral code that guides them in their decision making, their value judgments, even their leisure time. Blues enjoy being "good." Of all the personality colors, Blues come equipped with the strongest sense of integrity. A Blue would rather lose than cheat. Blues are trustworthy. Blues are the people who should be in position of power, but seldom are.
