Colours of the flag

According to the aforementioned law adopted in 1990, the colours of the flag are karmir, kappoyt, narndjagooyn (Eastern Armenian pronunciation), which translates exactly into "red, blue, orange".

The flag represents the people of Armenia. The red stands for the blood shed by all Armenian soldiers, present and past. The orange stands for the fertile land and the farmers who work on it. The blue stands for the sky.

Some other different interpretations of the colors of the Armenian flag are:
1) A rainbow over Mount Ararat.
2) Red is the blood shed and the whole is derived from the colours of the banners of the former Kingdom of Cilicia.
3) A simple description of the colours says: vermilion red, ultramarine blue and apricot orange.
4) A friend told me that he has heard: red: blood shed; blue: eternal land of Armenia; orange: courage.
5) Finally a source not to be neglected, the Embassy of the Republic of Armenia in Ottawa (although I find this one very awkward): red: the sun's energy; blue: the clear sky; orange: the wheat at harvest.
