Underwater Color LossRead Now
Most people are amazed by the multicolored fishes that they see in aquariums. Many wonder how such fishes can survive in the wild. After all, aren’t those bright colors on their bodies like a bull’s eye for predators? What must be remembered is that different wavelengths of light are absorbed by water to different extents. The most extreme case is that of red light. In the video below Kendall Roberg shows how colors change the deeper you dive. The video is about selecting the right fishing lure, but it demonstrates that as depth increases, the the color red is perceived as red to a lesser degree (because there is less red light to reflect) until it comes a point when it appears black. Other colors are also affected, but not as much.

Yes, when we think about color we seldom consider the effects of the medium through which light travels on the light itself. If the medium (in this case water) absorbs the a particular wavelength of light, then the color represented by this wavelength is modified or even disappears! Thanks for your comment, Yogesh.
