I was just stating a fact about colors of light penetrating water. I wasn't trying to speculate as to why one color catches fish at certain times and another will not. I don't know for sure as to why what you're saying is true but it is true a good part of the time. When it comes to fishing for predatory fish at night I was always under the impression that noise and disturbed water (such as most spinnerbaits are intentionally designed to create) is more important than color but that is not always true in all instances as well. Perhaps to a fish that spinnerbait you mentioned will appear a more natural shade of black or grey when submerged in water at night hence the good bites that can occur with them. Of course I'm just speculating because I have no way to know exactly what a fish may be thinking. I do know that no saltwater fisherman that knows what he is doing is without a large assortment of lures with the color blue in them for the sole purpose of being more visible in deeper waters. Since it reflects practically all colors of the spectrum including both red and blue white is another popular color for fishing in deeper waters. Being a avid snorkel diver in my younger days I also know that anything red will quickly turn to black or gray when submerged in water and anything blue will stay blue or at least it did for as deep as I was able to free dive. The following link may shed some light (LOL) as to why so many creatures that are prey for predatory fishes are red or black or have said colors as part of their color scheme. http://oceanexplorer.noaa.gov/facts/red-color.html
