Numbers 4:6

6and they shall cover it further with a veil of violet skins, and they shall extend over it a cloth made entirely of hyacinth, and they shall draw in the bars.
4:6The word ‘ianthinarum’ certainly signifies a different color than ‘hyacinthinum.’ The former also appears to be the natural color of the skins (type of skins is unknown), whereas the hyacinth color was most likely derived from the flower so as to dye a cloth (perhaps silk).(Conte)
