Legat, 1634.1 quotations
Yellow is so called from the Italian word Giallo, which signifieth the same ; Giallo hath his Etymology from Geel the high Dutch, which signifieth lucere, to shine, and also hence commeth Gelt, and our English word Gold, in French Jaulne, in Spanish Ialdo, or Amarillo, in Latine Flavus, luteus, of lutum, in Greeke ξανθὸς so that blacke, white, and yellow according to Aristotle are the foure primary or principall colours as immediately proceeding from the elements, and from those all other colours have their beginning.
Your principall yellow be these.
