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.

Dutch Orange is the Netherlands' most visible national color, from King's Day to football fans' shirts. It comes from William I, Prince of Orange, who led Dutch independence in the 16th century. On King's Day, Amsterdam streets flood with orange.

Krishna Blue comes from the skin color of the Hindu deity Krishna. "Krishna" in Sanskrit means "black" or "deep blue." Indian philosophy holds that blue represents infinity—the sky and ocean are blue, and all infinite things are blue. Krishna's blue skin symbolizes his transcendent, infinite nature. This is also the signature color of Jodhpur, India's "Blue City."

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.

The 30+ step dyeing process transforms fabric from yellow-green to deep blue through oxidation.

Iznik Blue is one of the Ottoman Empire's most glorious artistic achievements. 16th-century Iznik pottery fused cobalt blue, turquoise, red, and green. The secret was a unique quartz base (80% quartz) giving glass-like brilliance. The Blue Mosque's 20,000 Iznik tiles radiate deep blue in morning light.
