Country flags can be versatile in terms of their proportions, colours, symbols and overall design. Each symbol, color or the proportion represents something deeper.
Every country flag has an underlying meaning to it which often dictates it’s ideology and values. When it comes to shapes and symbols, many flags feature a sun, moon or a star/stars on them. This also includes circles.
