Brisbane's iconic Story Bridge was illuminated yellow for the majority of the 75 years since it was built.
For a few years now, the bridge has been illuminated with different colours. Typically each lighting display on the bridge is to commemorate a special day in history, raise awareness for charities and showcase upcoming events. Here are the most common displays:
One of the vast array of colours used during the Brisbane Festival fireworks.
Purple (charities such as Bravehearts Day, Epilepsy awareness Purple Day or Elder Abuse Day)
Rainbow for any LGBTI causes.
Green for Australia Day and any number of Australian sporting events or causes.
Orange for "Colour the World Orange Day", a cause for nerve pain awareness.
Red for "Red Bow Day" (the annual fundraising campaign for Muscular Dystrophy Queensland)
