You will never match the Xenons or LED for colour unless you want to reduce output a lot. Some of the bluer bulbs have quite a blue tint about them (more like a blue set of shades than a truly blue/white light output), really cuts back on the output though compared to the Osram nightbreaker series or Philips Extreme visons. Nightbreaker plus can be had quite cheap through one of the Amazon affiliate sellers or Eurocarparts, they are noticeably whiter than stock bulbs, but don't come that close to Xenons. For how long they're on for and output, Nightbreakers are fine.
