Minecraft wiki entry for Unused_textures, associated text: When Java Edition 18w15a expanded on biome-dependent water tints (and made the water textures white to accommodate this), the subject biomes still remained limited, as swamps and different temperature oceans were the only[verify] biomes to have colors which differed from the default color specified. These colors were values explicitly specified per biome, rather than taken from a colormap like watercolor.png. As a result of this approach, there are currently several oversights in the current game where special water colors have not been defined for certain biomes even when they should be.[29]
