How about Robbin-egg blue

"Yet it's the unlikely "robin-egg blue" that surprises most paddlers. Because it contrasts sharply against most sea kayaking backgrounds it too is highly visible."
I recall reading that on a few different sites where someone might have actually done research. I'm too lazy to look for it now but I'm sure the research is out there. At least it is safe to assume that someone doesn't think that red and yellow are the most visible colors. It's probably because of how the eye takes in different frequencies of light and how blues are seen as brighter for what is really the same luminescence. Or something like that.
Get a camo boat. Camo always looks cool.
