If you go underwater with a night vision potion on, it is * tremendously* blue, so much that it is hard to see more than about 15 meters in front of you. This is with my render distance on far. I do not believe that this is a problem involving game modes, because I replicated this problem on creative mode. I also do not believe that this is a problem with OS, because I replicated this on ubuntu.
Use a respiration enchanted helmet for a better view.
