what colors fish can see

[DESTROYER]

Drew Clarke who now is an avid diver and teacher told me he takes a Roma Tomato down with him when he is teaching and 9 out of 10 times the people guess that it is a Kiwi.

I'm color blind and I got to tell you, I've always been more of the right place at the right time with the right presentation.

exactly, fish see tones after about 40' down, not so much in colors

I think the reason you see green lights being used is because thats the only color available in a 12 volt submersible. All the white lights I see are above the water and run on 110 via generator, the noise gives that away. I can not debate white vs. green because I have only used green, but I will say it works very well. I have seen commercial light boats with green lights above the water.

Actually what we humans see underwater is tones (as colors fade with depth). And considering that it is believed that fish can see not only the colors we can, but the UV spectrum too, it only makes sense that there visual perception is much different that ours.

We can come up with computer models/simulations for what it might look like, but a brains perception, whether it's a fish, snake, elephant, bird, or fish can not be duplicated, all we can do thus far is to take our best guess based on what little information we do know.
