Yeah, just get two of these:

Just kidding!
Actually, without knowing anything specific about these lamps other than the fact that they're parabolic-reflector lights with fluted lenses and that they take H3 bulbs, I'd have to recommend just sticking with good quality clear 55-watt H3s from a trustworthy manufacturer.
All else being equal, yellow fog lights are better than clear fog lights. But, I don't know if there's a good way to make these fogs yellow. The vast majority of yellow H3 bulbs use a dichroic coating (the bulb actually looks bluish when not turned on), which can cause some weird behavior with the optics. It can actually result in bluish light being thrown above the cutoff, which is exactly the worst thing that can happen to a fog lamp.
If you managed to find an H3 bulb with an old-school yellow tint on it, then you wouldn't have this problem. I don't know where you could find one though. And, you'd have to deal with reduced light output, since tinting bulbs hurts their efficiency. In general you don't need a lot of light with fog lights (
definitely don't use overwattage bulbs), but that doesn't mean reducing the light source's intensity won't hurt their performance.
Then again, I believe in the state of California it's actually illegal to use fog lights without having the headlights' low beams on, which kind of defeats some of the purpose of fog lights. If you plan on following the law, then it probably doesn't matter too much what you do with the bulbs.
But I still recommend good standard H3s. That's what the lights were designed for, and it's probably what they'll perform best with.
