It is the function of art to renew our perception. What we are familiar with we cease to see. The writer shakes up the familiar scene, and, as if by magic, we see a new meaning in it. - Anais Nin (Art - M.C. Escher)
The colour amaranthine came from the Greek word ‘amarantos’ which meant unfading. The word Amaranth was used to name an imaginary, undying flower that was, presumably, a deep red-purple colour and there you have the two uses of the word today. Lovely stuff.
