@saab,
"Orange" for "Apfelsine" is used in German since the 18th century. (Apfelsine first was called "Apel de Sina" = apple from China)
Both words are used today equally - but before 'Orange' it was "Pomeranze" (my maternal grandmother still used that word)
Pomeranze comes from 'pomo' (appel) and 'arancia' ("gold apple" [= aranzo > orange])
The colour originally was called "orangengelb" ('orange yellow')
