In traditional pre-Islamic Turkic culture, both blue and green were represented by the same name, gök 'sky'. The name is still in use in many rural areas. For instance, in many regions of Turkey, when mold is formed on cheese, the phenomenon is called göğermek 'turning into the color of sky (gök)'.
