For beta 1.7.3 and STAPI!
Biome Water
Simple mod adding biome water tint, working in the same way as vanilla grass and leaves tints based on climate.
- This mod uses modified colour map, instead of one left by Notch in game files.
I tried to tweak dynamic texture code as best as possible, to reasemble vanilla vibrant and light texture, and also allowing tint. Not a fan of dark water in similar base class mods.

Texturepacks
It's easy to change colour map yourself with texturepack, by modifing misc/watercolor.png file.
If you change texturepack with watercolor.png, when world is already loaded, you will experience graphical glitches. Simply reload your world.
Compatibility:
Mixins into:
LiquidBlock.classArsenicStillWater.classArsenicFlowingWater.class
Mod works only on StAPI as it's mixin into StAPI's own renderer. Should work on any StAPI version with same Arsenic renderer.
I have almost complete babric no-stapi version on disc. If there's interest I could share it.
Didn't tested with custom water textures from texturepacks, as simply I didn't have one to test with.
