RE: Warmth/Color of lights...
#1 - We've had 6 Tesla vehicles total. In the vehicles that have a DARK (black) headliner, the overhead dome lights have always appeared to be a warmer, more orange hue. In the light headliner vehicles, the dome lights have always appeared to be more blue, cooler. This may just be in our heads, but my wife was actually ho noticed it first and I concur. As such, IMO, the dark headliners have warmer interior OE lighting from Tesla.
#2 - WARM WHITE is the version that I got, based on the above info. It is definitely a more natural, warmer, more "orange" glow if you will. The color is more what we all think of when we think incandescent lighting, really. I was afraid that the "cool" white would be too blue, and since I have a dark headliner, I assumed the warm would match my warmer interior lights. Plus, I tend to personally prefer the warm over the cool spectrum of bulbs, but that is just my preference obviously.
Hope this helps those who are asking!
