Bug report: the tank doesn't use the color multiplier.
Proof: http://imgur.com/a/jdG46#0 (the ender tanks and the translocators are there to show what it should look like)
The liquid is Tea from the Avatar mod, source can be found at https://github.com/KeplerGaming/Avatar-the-legend-of-Steve. If it's a derp on my side or I'm wrong please tell me. All the mod versions used are in the description of the album.
