Yes there is orange too, which is Type I de-icing fluid. This is quite thin in consistency, and applied hot to remove existing snow and ice deposits on an aircraft.
The green stuff is Type IV which is anti-icing fluid, this is much thicker and applied to keep the surfaces clear of falling precipitation.
