▼5:7The color purple is repeatedly mentioned in the Book of Daniel as being associated with wealth and royal power. This is because the purple color of ancient times was obtained, in a time-consuming and laborious process, from a certain gland in certain types of shellfish. Thousands of these shellfish were required to produce a small amount of the dye, and so the dye was expensive and rare, and usually only found with the very wealthy or the powerful. This color is often called Royal purple, because of its use by kings, or Tyrian purple, after the city which was a center of production and commerce for the dye.(Conte)
