What is the meaning of the color Blue?
Ancient Egyptians were among the first to produce blue pigment, creating Egyptian blue from copper and sand around 2500 BCE for use in tomb paintings and decorative objects. The color became strongly associated with royalty and the divine across medieval Europe, where ultramarine — ground from imported lapis lazuli — was more expensive than gold and reserved for paintings of the Virgin Mary. By the 18th century, synthetic Prussian blue, discovered in Berlin around 1704, made the color widely available to artists and dye-makers for the first time. In 1890, Yves Klein later codified a specific shade as International Klein Blue, registered as a trademark in France in 1960, anchoring blue firmly in the vocabulary of fine art.
