I play with Optifine which allows me to turn off swamp colors (personal preference) however I was building with the water bricks in the swamp biome and noticed they did not match the water. It would be great if there was a config file that allowed for turning off swamp colors on certain Blockus blocks! (I don't know if the swamp affects any other blocks?)

This is a bug with Optifine, since the color of water bricks always matches the color of water.

Water bricks no longer change with biome colors
