A person's favorite color, favorite animal, and favorite flavor of ice cream can say a lot about them when considering the answers as a whole. Some prime examples I've heard are:

~ Pink/Yellow, Putu Bird, and Cotton Candy.
~ Light Brown, Tree Kangaroo, and Rum Raisin.
~ Green, Pig, and Cookie Dough.
Mine are:
~ Burgundy, Fox, and Moose Tracks.
