No matter where you are in the world, when a flag bearing a rainbow appears, you know exactly what it represents: the pride of the LGBT community.
The flag was created by Gilbert Baker in San Francisco in 1978 and was initially made up of eight colours, each representing a concept. Pink stands for sexuality; red for life, orange for healing, yellow for light, green for nature, turquoise for art, blue for harmony, and violet for human spirit. For commercial reasons, turquoise and pink have since left the flag, so today it officially only carries six colours.
Because of its simplicity and representive nature, the choice of a rainbow flag is perfect. The message it carries about human diversity is invaluable and it continues to establish itself as a worldwide symbol.
