Funny, I hate to do this, but that is a narrow band Hydrogen Alpha image. I'm a bloody astronomer and deal with light all the time. My point being is that if you keep refering to daylight being orange your off the mark a little. The car manufacturers set the light at 4.3k because our eyes work differently in low light. We actually see in mainly black and white at night, out colour receptors stop working in low light and therefore they compensate for it a little.
Anyway, as I said, I'll give them a go as they just arrived.
