Light from our Sun and other sources is all around, bringing colour, heat and energy. Over time, humans have harnessed light to create fire, fluorescent light and even scientific equipment like lasers. But light and colour are tricky. Too much or too little light changes our body chemistry, when it bends it can fool our eyes, and it can even act like a wave or a particle! Explore what First Australians and scientists have learned about the incredible properties of light and colour.
