There is no way you will get accurate colour over the internet. Between your camera and your screen, the colour will be all over the place.

Like trying to determine which exhaust sounds better by listening to a sound clip.

Remember that the higher the temperature, the less effective light that is put out. That is why audi uses 4300 to 4600K. That is the most effective range for actually seeing stuff at night. I replaced my bulbs with 5000K, looks much whiter than OEM which had taken on quite an orange hue.

 

I think When I do mine, I am going to replace them with 6000K, but am still undecided. I wouldn't mind the appearance of 8000K, but the light output is what I am really after. After riding in my friends B7, HID's are a must in my book. That thing lit up the road like it was a construction site!
