Green Diff Fluid?

I have a howl in 4WD. As a first diagnostic step I figured that I would check the differential fluid level. While the level was OK, the fluid was green. The consistency seemed fine, but the color was a pretty vivid green color - almost like antifreeze. What could have caused that?
 
Looks like shockproof lightweight oil. It just came with color additives to be different.

Just check for milkiness which could mean there's water in there.
 
clean gear oil will have a greenish tint to it. as long as its not dark like used motor oil or looks like chocolate milk, doesn't smell horrible, and has no pearly look to it from fine ground metal shavings, you're good to go.
