🟦 The Discovery and Historical Significance of Blue

Blue pigments have a rich history dating back to ancient civilizations. The earliest known blue pigment is Egyptian blue, created around 2500 BCE by the ancient Egyptians. This pigment was made by heating a mixture of silica, lime, copper, and alkali to produce a vibrant blue color. It was used in tomb paintings and statues to symbolize the heavens and the afterlife.

In the 6th century CE, ultramarine was introduced, derived from the semi-precious stone lapis lazuli. The name "ultramarine" comes from the Latin ultra mare, meaning "beyond the sea," as the pigment was imported from Afghanistan. It was highly prized during the Renaissance and was often used to depict the robes of the Virgin Mary in religious art .Wikipedia+1Architectural Digest+1

In the 18th century, Prussian blue was discovered accidentally by German chemist Johann Jacob Diesbach. This was the first modern synthetic blue pigment, leading to the development of other synthetic blues like cobalt blue and cerulean blue.
