The photo was taken in the 70s. It was a twin set in a shell, the tanks were inverted and the valves were very easy to reach. the take off was still on the top.

The suit and shell, friends told me they could not lose me...even thou they tried

Looks like someone cut his surface supply hose, that must be why he is up holding the reg.


But he looks very 'James Bond'

Can't be all bad ... he's got a FENZY

A good review can be found in: Adolfson, John. Perception and performance under water / John Adolfson, Thomas Berghage. New York : Wiley, c1974.

The section on color discrimination under water is pages 82 to 88.

Quoting Kinney, Luria, and Weitzmen (1969) on page 85:

A. For murky, turbid water of low visibility (rivers, harbors, etc.)

1. With natural illumination:​

a. Flourescent yellow, orange, and red.​

b. Regular yellow, orange, and white.​

2. With incandescent illumination:​

a. Flourescent and regular yellow, orange, red and white.​

3. With a mercury light source:​

a. Flourescent yellow-green and yellow-orange.​

b. Regular yellow and white.​

B. For moderately turbid water (sounds, bays, coastal water).

1. With natural illumination or incandescent light source:​

a. Any flourescent in the yellows, oranges, and reds.​

b. Regular yellow, orange, and white.​

2. With a mercury light source:​

a. Flourescent yellow-green and yellow-orange.​

b. Regular yellow and white.​

C. For clear water (southern water, deep water off shore, etc.).

1. With any type of illumination flourescent paints are superior.​

a. With long viewing distances, flourescent green and yellow-green.​

b. With short viewing distances, flourescent orange is excellent.​

2. With natural illumination:​

a. Flourescent paints.​

b. Regular yellow, orange, and white.​

3. With incandescent light source:​

a. Flourescent paints.​

b. Regular yellow, orange, and white.​

4. With a mercury light source:​

a. Flourescent paints.​

b. Regular yellow, white.​

The most difficult colors at the limits of visibility with a water background are dark colors such as gray or black.

From a lightsource, green light is apparently the one that you will see best in the dark. We actually did some tests with white, red and green light when I was in the army, and its not coincidental that those are the colors of light we carried around (1 flashlight with green and red filters). Green light is VERY easy to spot from far away. White light is also quite easy to spot and its a lot better to use if you actually want to see something in the light and not just be seen.. Red light is.. Well used during "light restrictions" so I guess that says about what there is to say about red light and darkness..

When diving I do tend to see bright/fluorescent green and yellow first..

I am very disappointed.... I was hoping that neon pink would rank first... Then I'll go and buy my hotpink suit, fins, mask, and tank!!

I was diving solo :scared:

Fuscia....definitely fuscia

I voted "yellow", but in a series of night dives when three of us had identical laser lights of red, green or blue, the green was the most visible.
