Ash,
I put 35W 6000K on Wifey's Eclipse a few months ago. They are true white with no hint of blue. IIRC, going to the 50W ballast caused the spectrum to shift higher so 6000K with the 50W will look more blue.
The only problem we've encountered is that 50% of the time when you turn on the lights, the driver's sided doesn't come on. Just turn the lights off & then back on & all is well. Still haven't figgered out why it's happening.

BTW, you can get away with low beam only version. The lights are bright enough that you prolly will never need high beams.
