Worth pointing out that modern Greek has borrowed a lot of words from other languages, including the Romance languages. For instance, the color grey is 'γκρίζος/grizos', from the Romance language words for gray (the more ancient alternatives would be πολῐός/polios and φαιός/fios, with only the latter surviving to modern times). I assume 'γαλάζιο/galazio' is somehow related to Spanish/French azul/azur as well, but can't find any sources.
