Even thought I have never seen green de-icing fluid I would say its deicing fluid

Looks like the old Eythel Glycol de-ice fluid, or the same stuff that you put in car radiators.
But that stuff AFAIK wasn't supposed to be used anymore because it tends to poison things.
I wasn't aware that colors of de-ice fluid had been standardized.
OBAMA-WORST PRESIDENT EVER....Even SKOORB would be better.

Actually the green stuff isn't "de-icing" its "anti-icing". The orange stuff is for de-icing. The green stuff sticks to the airframe longer therefore affording a much longer hold-over time.

Looks like someone wasted a lot of type IV. It should be on the wings and empennage only. Hopefully they didn't use it for De-Icing- the surface must be cleaned with type I first, then Anti-Iced with type IV.
I love the rumble of a 727 takeoff in the morning!

Ethylene Glycol De/Anti-Ice Fluids remain in use, however it is not used as much because of environmental concerns. As far as I Know, the Isopropyl Alchohol/ethylene mixture (Type II) is no longer in use commercially.
The modern De-ice fluids consist of Propylene Glycol, with type I typically a low viscosity fluid that is mixed with water, then heated to 170- 180 degrees F to melt snow and ice. it is orange in color.
Type IV is used full strength, and has a thickening agent to allow it to stick to the aircraft surfaces. It is green in color. The thickening agent has a shear factor, so that when the airspeed increases the fluids breaks down an runs off the wing. It is used during periods of freezing precip as a protective layer to prevent refreezing of the lifting surfaces. it is also very expensive, so the use of it is determned by whether the extra hold time is needed.
Hope this helps

We use Killfrost here too, it is type IV though, and we use it 100%. Killfrost ABC-S. I don't know if yours is a different version...?

Lufthansa seems to be using the green kind. It's cool to see how the fluid stays on the aircraft's skin pretty well, giving lufthansa that new cool livery people are talking about

It looks like a thin film of paint over the inner Zinc Chromate primer showing thru
