Fixes Fluid Color Render

Adds some color to the fluid rendering :wink: 

Only one I couldn't colorize based on the FluidStack is the Refinery Gui as I used what was available, which was a Fluid not a FluidStack. Hopefully that wont be a huge fix threshold

@CovertJaguar  These changes work for you? :smile:
