Blue is a hue that is frequently used to symbolise togetherness. Different hues, such as green and brown, are used to symbolise oneness in other spiritual activities and other types of traditions. Because of their connection to the Earth, green and brown are chosen.
The colour blue is associated with unity because it is said to reflect calm and tranquilly, which are essential qualities of unity. Other core qualities of unity are supposed to be represented by the hue, including hope, loyalty, and friendship. Blue is used in the flags of various countries, such as Malaysia and the European Union, to symbolise the people’s togetherness.
