Al,
I did. What got me thinking about this was the Gore-Tex/Sitka line of clothing that was developed for deer/elk hunters. I belong to an online marketing group for WL Gore, and they have been using that forum for experimenting and testing the actual gear. While it is now very public stuff, the research they were showing us a while ago was pretty convincing that the color schemes they are producing do go along way to providing a great deal of background matching, based on what they are saying is the actual color scheme in which those critters see. Of course, if they are fudging the baseline science about what goes on in the eyeballs/brains of those animals, all bets are off. But, assuming it's all legit, I was convinced that such camouflage would be a good investment. So, when I saw the flambeau stuff, I got to thinking. What I would like to see is a photo that approximates a duck's 'real-time' vision, such as it is a mix of the visible and UV spectrum (to a certain degree). The photos in the catalogue seem to be overly heavy on the UV light and markedly lacking in the visible. If it is such that ducks really do see in that manner, I can see such a paint scheme as providing a real advantage. I have noooo idea about whether or not such a pigment can be readily added to existing paints or if it is a different product altogether, though. Do you know something beyond what the Flambeau folks are saying?
