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 glow because they have different chemicals in their bodies. When combined, there's a chemical reaction and they glow. To be more specific, cells in the firefly's abdomen produce luciferin and that creates luciferase, an enzyme.The luciferin combines with oxygen and forms oxyluciferin, which is inactive, but luciferase speeds up the reactions.ireflies of different species glow in different colors. Some glow  in bright yellow, some in green, some in yellowish-orange, and  others in greenish-yellow. Some scientist â¦ s believe that the glow  color combined with their body color helps them stay undetected by  predators.
