Koi fish are commonly associated with the colours black, white, red, gold, and blue. Black koi represent adversity and are used to describe triumph over adversity. White represents professional success. Red koi fish is associated with passionate love, while gold is associated with good fortune and prosperity. Blue koi is the most masculine colour, representing male energy and fertility.
Here, our tattoo artists commonly recommend getting the red koi fish and the blue koi fish together.
