Humans across the ages have craved to master true blue. Ancient Egyptians came up with Egyptian blue, the first synthetic pigment. In the 19th century there was a race to create a synthetic ultramarine and then a synthetic indigo. And in the 21st century, the fascination continues as a group of researchers working in different fields is trying to create new blues: A plant biotechnologist funded by Japan9s largest whisky producer is trying to create a blue rose. A geologist in the United Kingdom…

Discovery of a natural cyan blue: A unique food-sourced anthocyanin could replace synthetic brilliant blue
TLDR
Computer simulations and large-array spectroscopic techniques were used to determine the 3D chemical structure, color expression, and stability of this previously uncharacterized cyan blue anthocyanin-based colorant and demonstrate the power of a multidisciplinary strategy to solve a long-standing challenge in the food industry.
A metal-free blue chromophore derived from plant pigments
TLDR
By extending the π-system of betalains, this work designed a photostable and metal-free blue dye named BeetBlue that did not show toxicity to human hepatic and retinal pigment epithelial cells and does not affect zebrafish embryonal development.
Hibonite Blue: A New Class of Intense Inorganic Blue Colorants
TLDR
A significant advantage of hibonite blues over cobalt blue is the substantial reduction in carcinogenic cobalt content while enhancing the color properties at a reduced cost for raw materials.
