The color is completely irrelevant.
Nissan, Toyota, Mazda, Honda, Hyundai, Isuzu, etc all use some version of a HOAT (hybrid organic acid technology) that is silicate free and borate free. It uses phosphate instead of silicate. It also contains no 2-EHA, which is used in - for example - Dexcool as the Asians believe it comprises elastomers and gaskets.
The only common aftermarket product is Zerex Asian Vehicle Antifreeze. However, it is a 50/50 premix with demineralized water, so using it for a full flush and fill is something of a problem.
Since they are basically all the same, you can buy any of the current Asian OEM coolants by price alone and use it in the Nissan.
