deep blue something (13. 574)

Via Quantum of Sollazzo and deliciously reminiscent of the harried and hued colour profiles appearing in the Paris Review and the Awl right before folding, we are directed to this delightful project chasing down the paper trail of pigments, one colour per day with its chemistry, provenance and poison. There are over two-hundred fifty already indexed, like the pale jade glaze originally from ancient Chinese ceramic-making techniques, this greenwear copied by Korean and Japanese artisans (the greyish shade comes from oxidising iron during the firing of kilns, Fe₂O₃→FeO, and the Western namesake is from a character in a popular seventeenth century French pastoral novel, L’Astrée by Honoré d’Urfé, who dressed in light green garb—no relation to the Celadons Ovid’s Metamorphoses or International Klein Blue, a synthetic ultramarine with connections to the Nouveau réalisme movement and among the first pigments to be successfully patented. Each entry has adjacent palettes and new specimens are posted Sundays. I feel like this is site I will return to often.
