Capricorns are known for being disciplined, responsible, down to earth, realistic, and hard workers. Their power colours are brown and grey, which are both neutral hues that are staples of any outfit or home. Brown is associated with seriousness and stability, and grey is known as being neutral, indecisive, in between black and white, steady, mature, and a little mysterious. This also describes a Capricorn, who isn't flashy yet is a cornerstone of any design.
