Only two countries use purple in their national flags-Dominica and Nicaragua

There are great varieties of designs and unique patterns when it comes to the national flags of countries and territories. Some countries have used bright colors like red, yellow, and orange on their flags but others have gone for not so striking colors. But the purple color is one of the rarest flag colors on national flags. Purple is a color of royalty and anyone would expect it to dominate most flags. However, only two national flags have purple on them, Dominica and Nicaragua. The two countries that use purple on their flag did not do so until in the late 19th century. Here are the two country flags with purple.
