What color is Ultramarine Blue?

What is the meaning of the color Ultramarine Blue?

The name comes from the Latin ultramarinus, meaning beyond the sea, a reference to the lapis lazuli stone mined in Afghanistan and shipped into Europe through Mediterranean trade routes from at least the 13th century. Renaissance painters ground the stone into pigment, and its rarity made it more expensive than gold by weight during the 14th and 15th centuries. Synthetic ultramarine was produced in 1828 by French chemist Jean-Baptiste Guimet, making the color widely available for the first time. The French navy adopted a version of the color for its uniforms, anchoring the shade to themes of authority and maritime service.
