Catacomb Bone

Catacombs

Catacombs are man-made underground passages primarily used for religious purposes, particularly for burial. Any chamber used as a burial place is considered a catacomb, although the word is most commonly associated with the Roman Empire.

Bone

A bone is a rigid organ that constitutes part of the skeleton in most vertebrate animals. Bones protect the organs of the body, produce red and white blood cells, store minerals, help regulate acid-base homeostasis, provide structure and support for the body, and enable mobility and hearing. Bones come in a variety of shapes and sizes and have complex internal and external structures.

Shades of white

Shades of white are colors that differ slightly from the CIE standard illuminant D65, a white point that represents the average color of daylight at noon. There isn't one objectively pure white, as noon daylight varies by location and atmospheric conditions, and the choice of using D65 instead of direct sunlight or a white point on the Planckian locus is arbitrary. For simplicity, this article will use the term pure white for the D65 white point.
