Purple Blade + White FoC Method

[ColdVizjerei]

I've done some digging around and it seems like the optimal way to get a purple blade is to wire a royal blue and red LED in parallel whilst using a resistor for the red.

My question is thus: To achieve a white FoC, would it be better for the 3rd LED color to be green or white? I know that mixing red + blue + green results in white, but would it result in the best white FoC? Those who have dabbled with this, could you give some input regarding which color you feel would be better or what you've used as a FoC color with a purple blade?

Just use a white diode for the FoC. It'll give you the exact effect you want.
