    Purple is the general name for the range of colors between blue and red. Purple represents royalty and nobility. Many people use words purple and violet for the same color. Purple shades generally have higher degree of red than blue while violet hues have more blue than red in the mix. Purple was the color worn by Roman magistrates; it became the imperial color worn by the rulers of the Byzantine Empire and the Holy Roman Empire, and later by Roman Catholic bishops. Similarly in Japan, the color is traditionally associated with the Emperor and aristocracy.
