Water Blocks have of a dark blue on the four sides while looking at them through glass blocks. When looking up and down through them, they have the proper color of the biome they're in, but not their sides. When looking through other transparent blocks, the color was unaffected. Each of them displayed the same color of the water according to the ocean biome. The visibility was less clear while looking through glass blocks to. While using a barrier block, an ender chest, a stone slab, and an end portal as tests, the water you can see on the other side was not a dark blue color as glass makes it look.
