Color Me Purple

Purpura is the Latin name of a particular kind of shellfish which, when ground up, produces a bright purple dye, which in turn was taken from the Greek word porphura to describe the same sea creature. The word purpura later began to refer to the dye, and eventually the color of this dye. This dye was very expensive, and purple was considered a color of royalty throughout Europe. When this dye was exported to England, the word purple was imported into English as well. Today "purpura" is used by doctors to describe purplish discolorations of the skin.
