Adorning the cloaks and garments of royalty, the colour purple was often called imperial purple due to the close association. The word purple is a derivative of the original Greek porphura, the name of the Tyrian purple dye of antiquity extracted from a spiny snail. The pigment was extremely expensive to produce and only the very wealthy could afford clothes dyed the colour of grapes and plums. As a secondary colour, purple is wedged between red and blue on the colour wheel. The tones leaning towards the blue side of the spectrum were desired due to their association with the rare blue pigment favoured by artists and craftsmen.
