Grey is frequently associated with the idea of wisdom. This comes initially from the concept that an individual with grey hair is often considered older and wiser. In this same fashion grey can also be a color of maturity and honor. From a more negative perspective grey is a color associated with compromise (being neither black nor white) or even weakness (as something less than a color and more of a watered down or washed out hue).
