Fog light bulb replacement - colour options?

[Mesbo]

One of my fog lights are out. Two options:

1) replace with OEM

2) change it up and use something from the aftermarket to give a different colour

I'm OK with keeping it OEM, but would like thoughts on changing colour to match xeons? Also where to find bulbs?

Thanks

HIDs! Heh.

Yellow is nice, but is starting to get played out. I'll PM you a place for bulbs.
