The Fluid cows are rendering like normal ones (without the color tint).
I'm trying to figure out what mod is causing it, but I had no success so far.
It's neither Optifine, nor Quark.
The mod version I am using is 1.7.11.02a.
I attached a file containing the names of all loaded mods:

modlist.txt

I figured out that it is caused by Albedo
