Using the blinding or darkness effect underwater removes the characteristic blue filter of the water when submerged.

When using one of the potion effects that are blindness and darkness, when submerged in water it makes it not look like an aquatic area if you combine it with the night vision potion effect to be able to see better, it looks bad. In my opinion it seems that it is not entirely well done, I don't know if it is a mistake or something intentional but it looks very bad.

■ Expected result: When entering the water with the mentioned effects you can see the blue filter and the area appears aquatic.

■ Result appeared in Minecraft: The potion of darkness and blindness effect removes the blue filter from the water causing aquatic areas to look horrible, seeming like an area without water.
