My Angel Eyes is definitely not blue. Check the pics here. I kept mine to default with the yellow OEM standard little light bulbs. CCFL is a completely different kind of lights, it's like a tube light which gives you a much brighter, whiter, and linear brightness across the ring.

My lights came with only the 4k-ish high beam bulb only.
