http://mustangsurvival.com/blog/2015-06/what-most-visible-color-can-be-worn-when-water?country=25 Since we've had a few discussions here recently about signaling devices, when I saw this I thought I'd share it here.
 
Do the results conflict with your on-water experience?

The results "feel" correct to me...

( Nice presentation, btw. Thanks. )
 
Perhaps Sea Hunt would have been more successful if the pigeons were flying the birds?

Landside, Fire Departments went to that green for their response vehicles awhile ago, thinking the green made them easier to see in low light. They're all back to red.
 
FWIW, I've noticed for a long time , when I am returning through the harbor channel toward my marina in last light that the red nuns are definitely easier to see than the green cans . And I believe the old black cans were a bit easier to see in those conditions due to stronger contrast with the water. But that green is better than black in daylight.

I'm a bit surprised at Mustang's results with survival suit colors. I kind of like the emergency services -type green but think I'd rather be wearing bright day-glo orange if I were in the water in low light/ nighttime.
 
We had members from the 106th ANG Rescue Squadron, West Hampton Beach, NY, at our Power Squadron meeting, and they stated that green dye from the raft was easily spotted in air rescue situations.
 
I've only seen a dye marker once from sea level - and it was from some jackass doing jackass things. But it was very, VERY noticeable! Not sure of it's utility for a surface search, but since they're intended for visibility to aircraft, I can only assume they work well in daylight. No firsthand experience on aircraft searches - I don't have pretty enough hair or a sensitive enough nature to be an airdale. I'm a knuckledragging Lifeboat guy, I stay on the surface and get down and dirty instead of staying aloft in luxury. (There's a very good natured but very creative rivalry between the aviation side and the Lifeboat side of SAR. They assume we live in kennels when we're not underway, we assume they paint each others toenails when they're not airborne, and will die young from all the toxic hair products)
 
Most if not all road and maintenance workers now sport light green reflective safety vests in NJ. I started noticing this about 2 years ago.
 
There is a human factor issue in color recognition. The human eye can differentiate more shades of green than any other color. There is a reason for this and it is both environmental and evolutionary. The earth has lots of chlorophyll, in various stages, emerging, rich, and dead. As hunter-gatherers we had to be able to distinguish shades of green to feed ourselves. Everything from looking across a hill for berry bushes to hunting prey to avoiding predators our eyes have developed to distinguish shades of green more than any other color. A lion for instance is actually the color of dead chlorophyll and thus is a shade of green, green being yellow and blue in varying mixtures. The fluorescent green is the most easily distinguished of all shades of green because it is the least naturally occurring shade of all greens.

Bill the thought is to make the worker stand out from the road barrows that are orange.
