The colours of Zeus symbolize power, strength, and justice. According to Greek mythology, Zeus was most commonly seen wearing a white chiton (tunic) and blue himation (cloak/robe) and was sometimes seen with other colours as well.
White: White is often seen as a sign of purity. In relation to Zeus, white symbolizes his purification and his godliness.
Blue: In Greek mythology, blue is associated with the sky and heaven. Thus, the blue colour of Zeus' himation symbolizes his sky god status and his connection to the sky.
Gold: Zeus was sometimes seen with a golden scepter in his hand, representing his authority and sovereignty as king of gods.
Purple: In Ancient Greece, purple was a colour usually reserved for royalty. Thus, purple likely symbolizes the power and authority of Zeus as the ruler of the gods.
Red: Red is traditionally thought to represent courage and strength in Ancient Greece. As the most powerful of the gods, red symbolizes the strength of Zeus and demonstrates his willingness to fight for justice.
To conclude, the colours of Zeus—white, blue, gold, purple and red—are indicative of his purity, power, and strength.
