Pan-Arab colors
The very first time these colors were used together was back in 1916 when the flag of the Arab Revolt was designed. The flag was a simple design involving three stripes of black, green, and white from the top respectively. The red color is in the shape of a triangle originating from the left side. Presently, there are several flags that utilize these colors. These flags include those of nations and regions such as Jordan, Palestine, Kuwait, the United Arab Emirates, and the Sahrawi Arab Democratic Republic. The brief union that was known as the Arab Federation of Iraq and Jordan also had a flag that used the colors.
