Iznik Blue

Persian Blue is the most iconic color of Islamic art. Isfahan's mosques, "half the world," have Persian blue tile domes gleaming like sapphires in desert sun. The complex process involves grinding cobalt ore and firing at 1200°C. Persian blue traveled the Silk Road to China, inspiring blue-and-white porcelain.

Turquoise is named after Nishapur's mine in Iran—"turquoise" means "Turkish" in French, as the gem reached Europe via Turkey. Persians believe turquoise brings luck and wards off the evil eye. Persian mosque domes often alternate turquoise and deep blue. Imam Reza Shrine's dome in Mashhad is turquoise, gleaming like a gem.

Japanese indigo is celebrated as "Japan Blue." Hokusai and Hiroshige's ukiyo-e extensively used this deep blue, stunning European artists after Japan's 1853 opening. Van Gogh collected Hiroshige prints, and "The Starry Night"'s swirling blues were directly influenced by "The Great Wave off Kanagawa." The 30+ step dyeing process transforms fabric from yellow-green to deep blue through oxidation.

Egyptian Lapis was one of ancient Egypt's most sacred colors. Lapis lazuli traveled from Afghanistan to Egypt, valued like gold. Egyptians considered it the "stone of heaven"—they believed the sky was blue because of a massive lapis dome. Pharaoh masks, amulets, and tomb murals extensively used lapis blue. Tutankhamun's mask has lapis inlaid around the eyes. Egyptians ground lapis into eyeshadow—"Mesdematet"—possibly the world's first cosmetics. Cleopatra's blue eyeshadow was reportedly lapis powder.

Cobalt Blue is China's most globally influential color. In the Yuan Dynasty, Persian cobalt met Jingdezhen porcelain clay, creating stunning blue-and-white ware that spread along the Maritime Silk Road. A Yuan Dynasty blue-and-white jar sold for ¥230 million in 2005.

In the 17th century, the Dutch East India Company brought Chinese blue-and-white porcelain to Europe; Delft potters imitated it and developed a distinct local style. Delft Blue depicts windmills, tulips, and maritime scenes in serene cobalt.
