Black is a staple in my closet. Not sure I completely agree. "Black is modest and arrogant at the same time. Black is lazy and easy -but mysterious. But above all black says this: "I don't bother you - don't bother me.
black, with its absence of colour, is often associated with mystery and power. Black can often be intimidating and give off an ore of power/control. black is also used for classiness and sophistication - a staple colour in most of our wardrobes aswell.
