Introduced at about the same time as ultramarine, Cobalt Aluminate is a synthetic inorganic spinel. Spinel comes from the Latin word spinella, a diminutive form of spine, in reference to its pointed crystals.
In masstone it is a marginally cooler blue than ultramarine, with a fresh, lively appearance. The tints formed when white is added are wide ranging, being a good tinter - it produces a range of mid-temperature summer sky blues.
