I can't remember if it is UV lights or black lights, but someone should invent hand-held lights that really illuminate the coral, animals, etc.

Actually, a regular dive light will do the trick.

According to my instructor, water filters the "white" light from the sun in such a way that mostly blue/green is all that is left at depth. But if you carry a dive light, this is a white light source that should really show off the colors of the marine life.

And don't forget, someone is manufacturing masks with color correcting lenses. These are something that I definitely want to try.

Found something else about this topic...

At a recent dive club meeting, they showed off a dive light that throws the same "color" light as sunlight. Looks a bit weird in a dark room, but the results underwater were impressive. Presenter said you could also use this with your photography to get the bright colors of the coral and marine life.

Someone has designed a light that does this. It is called the Night Sea Ultra blue dive light you can click below to view it. http://diversdiscount.com/images/lights/ultrablue.jpg
