isabellina / isabellinus
Mod. L. isabellinus  isabelline-coloured, greyish-yellow  < French  Isabelle  < Spanish  Isabella. The origin of the colour term ‘isabelline’ is now unknown. The most likely candidate is Isabel I Queen of Castile and Spain (reigned 1474-1504), said to have promised not to change her undergarments until Spain was freed from the Moors (Granada, the last Moorish ta’ifa, fell in 1492). In 1600, a gown of isabella colour is referred to in an inventory of the wardrobe of Elizabeth I Queen of England (Macleod 1954). The link with the Archduchess Isabella, daughter of Philip II of Spain, who vowed not to change her linen until Ostend (beseiged 1601-1604) was taken, is discounted by SOED 1944 (cf. "I came across an alternative explanation, that the word 'isabelline' is actually a corruption of the Italian word zibellino. This name was given to a pelt of an animal such as a marten or Sable, worn by wealthy women during the 16th century. It may originally derive from an Arabic word meaning 'lion' and therefore mean 'lion-coloured'" (Stephen Moss 2017, Birdwatch, 299, 77)).
