Glowing in Several Colors. When fireflies give off light, they do so in a handful of different colors. These colors include vivid yellow, yellowish-orange, green and yellowish-green. Fireflies from different species often glow in different colors.
Fireflies produce a chemical reaction inside their bodies that allows them to light up. This type of light production is called bioluminescence. The method by which fireflies produce light is perhaps the best known example of bioluminescence.
