The red pattern on the white background on the left is a traditional embroidered pattern called a "Rushnyk." This pattern, which symbolizes wishes for prosperity and life, is deeply connected to Belarusian folk art.

While this is the current official flag, the historical white-red-white flag also holds significant meaning in Belarus. This historical flag is sometimes used as a symbol of the pro-democracy movement, making it an interesting point that the use of the 🇧🇾 emoji can sometimes carry a political context.
