Visual Glitch -
With the new snapshot, water changes colors according to the biome type. Lava also seems to follow this general pattern. I am not sure if this is intended, however, it seems strange. An example is in the "Beach" biome, it is the standard orange lava. But in the "Deep Cold Ocean" biome, the lava appears redder, and a little pale. I attached some photos below showing the issue (in spectator mode).
