What color is commonly associated with bioluminescence?

Bioluminescence, the phenomenon where living organisms produce and emit light, often results in colors that are primarily green or blue. This is due to the types of chemical compounds involved in bioluminescent reactions, where the emission spectrum is influenced by the specific biochemical processes. Organisms such as certain jellyfish, fireflies, and deep-sea fishes primarily emit light in these wavelengths, often because blue and green light can penetrate water more effectively than other colors. This makes these colors advantageous for communication, predation, or camouflage in aquatic environments.

The deep-sea habitat, where many bioluminescent organisms thrive, sees minimal light from the surface, making the emission of blue and green light especially effective. These wavelengths are less susceptible to absorption by water, allowing for greater visibility over longer distances in such environments. Therefore, associating bioluminescence with green or blue is scientifically grounded and consistent with observations of these remarkable natural phenomena.
