help with the little bulbs and fog lights under the xenons

[candywhite12]

hi all, under the bi-xenons there are bulbs with a yellowish color.  you can have those on with the fog lights w/o the xenons, or on with the xenons when the car is in auto mode.  In any case, the yellowish bulbs mess my gti's good looks    any recommendations on what kind of bulb to change those with, so that I get a similar hue as the xenon one?

also I would like to do the same with the fog lights, yellowish again, when on with the xenons it looks like 2 completely different colors - which they actually are

thanks
