How was Prussian Blue discovered?
Prussian blue was discovered around 1706 when a paint maker Diesbach accidentally synthesised the product while trying to make a red lake of cochineal, using a sample of a potassium contaminated with iron. It has a strong reddish blue colour, and its importance was soon recognised by the paint industry.
How was the color blue discovered?
Beginning in about 2500 BC, the ancient Egyptians began to produce their own blue pigment known as Egyptian blue by grinding silica, lime, copper, and alkalai, and heating it to 800 or 900 °C (1,470 or 1,650 °F). This is considered the first synthetic pigment.
Did scientists discover a new color?
Oregon State University chemist Mas Subramanian and his team accidentally discovered YInMn blue while experimenting with new materials for electronics. The color is named after its chemical makeup: Yttrium, Indium, and Manganese.
Who discovered blue?
Blue was first produced by the ancient Egyptians who figured out how to create a permanent pigment that they used for decorative arts. The color blue continued to evolve for the next 6,000 years, and certain pigments were even used by the world’s master artists to create some of the most famous works of art.

How was royal blue created?
By heating lime, sand and copper into calcium copper silicate, they discovered the royal-turquoise pigment Egyptian blue, which spread around the Mediterranean world and was widely used until about AD800. In China, copper was blended with heavy elements such as mercury to create shades of blue.
Why is YInMn blue so expensive?
YinMn is more environmentally friendly to produce than other blue pigments, and is less toxic than the cobalt-based blue pigments (Cobalt and Cerulean Blue). However, the pigment is very expensive to make due to the elements that it contains, and this makes it less accessible.
Who created YInMn Blue?
chemist Mas Subramanian
In 2009, researchers at Oregon State University discovered YInMn Blue—the first new blue pigment identified in 200 years—while developing materials for use in electronics. Led by chemist Mas Subramanian, the team quickly realized that it had stumbled onto something significant.
