After not being content that I was "100% sure" after looking at my own pictures (Captain Reliable), I took the car out of the garage and parked her in the alley. Comparing different types on driver and passenger sides. Well, turns out I like the warm white and in fact the pictures are nearly spot on.

While I do think the Natural White is actually the closest to 5000K, I don't believe that matches the stock bi-xenons the best. I ended up switching the Warm Whites in and am actually quite happy. A touch brighter would be....ok my **** retentiveness is showing.

Warm White, final answer

 

Definitely like to see these in person...next mini-meet!
