Etymology of INDANTHRONE BLUE

The word "indanthrone" is derived from a combination of "indigo" and "anthracene". "Indigo" refers to a blue dye that has been used for centuries and is obtained from several plants, particularly the Indigofera tinctoria. It is named after the Greek word "indikon", meaning "Indian dye".

The term "anthracene" comes from the Greek word "anthrax", meaning "coal" or "carbon". Anthracene is a hydrocarbon compound found in coal tar, which is a byproduct of coal.

Therefore, "indanthrone" signifies a blue dye derived from the compound anthracene, which is similar in color to indigo dye.
