mauve: [19] Etymologically, mauve is the colour of the ‘mallow’ flower. The word was borrowed from French mauve, whose original meaning was ‘mallow’, and which was descended from Latin malva ‘mallow’. English took over malva in the Old English period as mealuwe, which has become modern English mallow. And Greek molókhē ‘mallow’, a probable relative of malva, is the ultimate source of English malachite [16]. => malachite, mallow
