If you are hunting dark blue water, I want to vacation there! Seriously, duck hunting water is usually not blue. With the addition of the flat light for those "ducky days" I would be looking at grays, or mud browns, or white/ice. My scull float is light gray, the Kalash awaiting refurb is gray too. Sneakbox is dead grass green #28 FME and matches the water color where I hunt perfectly.
