Flags are very colorful and they can be used for identifying countries.
A flag is not just a symbol, but a way for a country to portray itself to the rest of the world. Very often, the colors used in a flag represent the values of that country (or other entity).
How can a country’s history, geography, culture, politics and religion be squeezed into one design?
Wars, revolutions, political unions and public competitions have shaped the colors and content of these most evocative of symbols. Colors within flags differ from country to country and state to state; the colors presented hold deep-seeded meaning and representation.
Black: Often used to represent determination, ethnic heritage and/or the defeat of enemies. It can also be used as a symbol of death or mourning.
White: Seen as a symbol of peace, purity and harmony, and has also been used to represent surrender in times of battle.
Red: Stands for power, revolution, vibrancy and war (symbolic of bloodshed). Other meanings include courage and domination, while it can also be viewed as an alert of danger.
Blue: Signifies determination, liberation, alertness and good fortune.
Green: Often seen as a symbol of agricultural influence, as well as prosperity and fertility. It can also be viewed as youthfulness and hope.
Yellow (or Gold): Has long been viewed as a symbol of wealth and energy, as in the sun. It can also be used to represent happiness.
