Mine are Silverstar Silvania headlight bulbs. They are slightly blue (of course not like HID's though). For mine, they advertised that it is slightly blue.

 

I have tried several sets. I have heard nothing but good about the Silverstars although I haven't used them and they arnt supposed to be blue. I have tried Eurolite Super Plasma's first for low and high beams. The low beams burnt out after about 2 months I figured what the heck and they were still under warrenty so I got another set thinking maybe I just got a bad set. Sure enough about 2 months later the second set burnt out. I then put stock bulbs back in. While they lasted they were a bright white maybe a slight hint of blueish purple but not a whole lot just really white and bright and were better than stock. The high beams lasted a little over 2 years I just recently had one burn out. I replaced it with the same bulbs as I like them a fair amount. The new ones you could tell from looking at the tint on the bulb that it wasn't going to be as purple as it didn't have as dark of a tint not that it was ever dark. Well I put it in and you could see a differnce between this one and the other one I had had for over 2 years this one wasn't as white more yellowish which the others didn't have any yellow at all these had a little. Still decent though and thats what I'm running now I don't know why they changed a perfectly good bulb though. I wouldn't reccomend these just because of the low beams burning out and I'm not as impressed with the new set but they are decent.
After getting tired of stock bulbs I then bought some Farenheit bulbs and put them in. During the day they still had a little yellow to them atlhough not a lot and most bulbs do during they day. It was white at night. Whiter than stock. They seemed a little brighter too. They may have had a little blue but not much if they did any they seem a lot like the Silverstars from all the things I have read and seen. These were better than stock also I would reccomend these unless you want a lot of color.
I decided later I wanted to have a little more blue to the lights so I got some Eurolite Xenon Crystals as I had a friend that had them in a van although she had high wattage ones and I got stock wattage ones so I Wouldn't melt the wires. Hers lasted almost a year. I'm hoping mine last longer but they may not. I put them in and they looked pretty blue with one in one side and a Farenheit on the other side. Keep in mind the Farenheit was whiter than stock anyway. It looked yellow compared to the Crystal light. After I put both in and got used to them they seemed a little less blue but really blue compared to other ones and still blue when looking just at them. I like them a lot I wouldn't say they are much brighter than stock though if any they look brighter looking at them but I wouldn't say the output is much better although it may be a little but I don't think so it's not a whole lot worse though if any. Here is a picture of the Xenon Cystal on the right and the Farenheit on the left now keep in mind I think the car is at an angle thats all I can figure out as the Farenheits arn't that much brighter and when I put both bulbs in the left looked brighter then also so I think the car is at a slight angle.

I have heard the Eurolite Fusions have even more blue to them although some say they have too much blue. I would get stock wattage bulbs whatever you do unless you upgrade the wiring as they will melt the wiring and some will melt the housings.

 

Here is my stock versus Farenheit comparison it's hard to tell but you can see where the Farenheits are whiter.
