Man at the dawn of civilization recognized that sunlight was essential to life. Color, being a manifestation of light, held divine meaning. Historical records of color show little interest in the physical nature of color, nor yet in its abstract beauty, but in symbolism that attempted to resolve the strange workings of creation and give it personal and human meaning. —Faber Birren
The color 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 color and there you have the two uses of the word today. Lovely stuff.
