I've heard that the design of the angel eye rings make the light color appear slightly warmer than the output rating. While this may be untrue, it would explain this phenomena. The LUX's LED's are rated at 6000-6500K, and the fog lights are rated at 6000K. I'd guesstimate that the angel eyes right now are around 5000K, and as such, the fogs don't quite match.
