Capricorn color: Brown and grey Earthy grey and brown help Capricorn find the strongest and most practical path to take in life. These strong but neutral colors enhance Capricornโs solidity, reliability, and traditionalism. A combination of extremes -- white and black -- grey increases the conservative nature of Capricorn and its no-nonsense approach to life. Brown represents stability, and can greatly benefit the Goatโs steadfast determination as it strives to reach its goals.
