Variant flags usually replace one of the stripes with a color that is significant to a specific branch of Buddhism. The final stripe represents the combination of all of those virtues into a single being. The blue stripe represents peace and universal compassion, the yellow stripe stands for the Middle Path, the red stripe represents the blessings that arise from practicing the faith, the white stripe symbolizes the purity of Dharma, and the orange stripe represents wisdom.
The colors are the six colors that were said to emanate from the body of the Buddha when he attained enlightenment, and each of them represents practice or value in the Buddhist faith. The final stripe contains all of those colors. The first five stripes are blue, yellow, red, white, and orange. The international Buddhist flag consists of six vertical stripes. Colors and Symbolism of the Buddhist Flag
Very few of the variant flags are used outside of their country of origin, so the origin flag remains in use throughout the world as an international symbol of Buddhism that can represent every sect and school of the religion. Most of them resemble the Buddhist flag that came into use near the end of the 19th century, but a few of the flags come from different traditions and bear almost no resemblance to the original flag. There are many different variations on the Buddhist flag for sale in different parts of the world. American States, Territories & Cities Flags
