The color name comes from Latin ultramarinus literally meaning "beyond the sea". This is because the color was made by grounding the mineral lapis Lazuli imported from Afghanistan, a country that lay beyond many seas.

A synthetic ultramarine pigment was created in 1826, the powder of which appears much brighter than the traditional powder obtained by grinding lapis lazuli.
