Why does obsidian have a black color?

Obsidian is black mainly because the internal minerals are composed of cryptocrystalline and vitreous, and the phenocryst is composed of white plagioclase. However, obsidian only appears black in natural light, it is actually a yellowish-brown inky gemstone under light transmission, and obsidian is not only black, but also visible in brown, gray and a small amount of red, blue and even green. Obsidian may be entirely monochromatic, or striped, or speckled, and some crystals may produce a "snowflake" effect or be seen as a shimmering iridescence. Obsidian is actually a black gemstone that appears black in natural light, but generally takes on a yellowish-brown inky color when exposed to light.
