Number of Countries Using the Symbolism of Three Vertical Stripes

Several countries have chosen to use the symbolism of three vertical stripes of equal width in different colors, specifically green, black, and yellow, for their national flags. The number of countries that can use such symbolism while having their own unique flag is not explicitly mentioned in the search results. However, it is important to note that many countries around the world use variations of the three-stripe design in their flags, but the specific colors and arrangements may differ.

It is recommended to consult a reliable source or conduct further research to obtain an accurate and comprehensive list of countries that use the symbolism of three vertical stripes in their national flags.
