Nulon Long Life Concentrated Coolant is Green & is a OAT Hybrid.... Nulon Ultra Cool 70 Plus is also green but is Glycol based...Yet they neutralize each other when mixed.

Coolants can be the same color but use different inhibitor packages. Each unique coolant chemistry formulation performs differently.
