Black is associated with power, fear, mystery, power, authority, elegance, formality, death, evil and aggression, authority, rebellion and sophistication. Black is required for all other colors that have depth and variety of hue.

The color black is the lack of color. Black is a mysterious color usually associated with the unknown or the negative. The color black represents strength, seriousness, power and authority.
