Turkic
The Kazakh language, like many Turkic languages, distinguishes between kök as the word for the color of the sky, the sea, and green plants, and jasâl as the color for man-made green things.
Turkish treats dark or navy blue (lacivert, from the same Persian root as English azure and lapis lazuli) as a separate color from plain or light blue (mavi). Mavi is derived from the Arabic word مائي mā’ī 'like water' (ماء mā’ being the Arabic word for water) and lacivert is derived from Persian لاجورد lājvard 'lapis lazuli', a semiprecious stone with the color of navy blue. In the pre-Islamic religion of the Turks, blue is the color that represented the east, as well as the zodiac sign Aquarius (the Water Bearer). A characteristic tone of blue, turquoise, was much used by the Turks for their traditional decorations and jewelry.
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 gögermek 'turning into the color of gök/sky'.
