From what I can find - all Honda's require silicate free coolant. You should use the Nulon Blue Coolant because it meets the Honda Type 2 Blue specifications and the Nulon Green doesn't. The official Honda Type 2 coolant is silicate and borate free.

"Some antifreeze, although labeled as safe for aluminum parts, may not be compatible with Acura cooling system components.
Extensive research and testing by both Honda R&D and CCI, the manufacturer of the Honda coolant, have proven that the abrasive silicates and/or borates found in most domestic coolants can cause these problems:
Silicates bond to the surface of the water pump seal and act as an abrasive, causing considerable seal erosion and coolant leakage.
Silicates tend to gel and settle in the coolest parts of the cooling system, causing radiator plugging and overheating
In contrast, Honda coolant was designed specifically for aluminum engines.
It contains an organic corrosion inhibitor instead of silicate. This superior formula gives these advantages: No silicate abrasion of water pump seals. For example, these graphs show the surface roughness of two aluminum water pump seal rings. Seal A, exposed to silicated coolant, shows considerable damage. Seal B, exposed to Honda coolant, displays only minute wear."
