Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order.

Suspected cause
Based on his description (headlights are whiter) I suspect he does have the HIDs though which would explain the color difference.

Suggestion
Back in the days of the 996 I could kinda understand it as HIDs were still just for the higher end cars and not prevalent (though that was already changing by the end of the 996).
Leading evidence: 'he does have the hids though' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'he does have the hids though' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Replace by the end of the 996)' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Fog light reflector assemblies are design to provide a low and wide beam pattern, the idea being to illuminate the close in roadbed so you can continue forward SLOWLY, not so fast as to over-run the illumination.

That's why night skiiers use yellow tinted goggles.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Only used them for the first time last night.
They look a dirty yellow color when turned in. Headlights are very clear white.
Is that normal for the fog lights? Different wavelength of light to cut through the fog I assume?
Are your headlights halogen or bi-Xeon?
The color differs on ours, but that's because the headlights are the bi-Xeon versus the halogen(?) for the fogs.
The Xenons look like (note the smaller lens towards the top of the headlight area):
The halogen will look something like this (couldn't quickly find a MkII halogen light):
The difference is the different bulbs types (fogs are not Xeon).
If you still have the original bulbs new ones would probably be brighter, but they will still be yellower than your low beams.
I found out that some MKIIs came with Halogen projector headlights - meaning that they look like HID Bixenons but they are regular H7 halogen bulbs behind projector lenses.
Really? That's annoying (from trying to figure out what you have).
Based on his description (headlights are whiter) I suspect he does have the HIDs though which would explain the color difference.
If you intend to use them as a true fog light, then a bulb with a lower color temperature (like the standard OE bulb) will provide better visibility than a "whiter" light. If you want to use them as driving lights or simply want a certain look, then try to find a bulb that has a color temperature closer to the OE HID lights, which is 4,300 K.
I was more interested if it is normal for those colors. Seems the color is correct for fog driving effectiveness. They really aren't bright enough for useful driving lights.
It is perfectly normal.
I only use mine in the fog, so I've got standard bulbs in there. For performance could be improved even more with a true yellow bulb, but I agree with you - they aren't very bright.
Fog light reflector assemblies are design to provide a low and wide beam pattern, the idea being to illuminate the close in roadbed so you can continue forward SLOWLY, not so fast as to over-run the illumination. Useless as driving lights.
The yellow/amber tint will give your human eyes more ability to define terrain better.
That's why night skiiers use yellow tinted goggles.
I always use -AW (All-Weather) bulbs, only in actual daytime foggy conditions,and ALONE.
I know, I was shocked that a $100K car could come with halogen projectors...I read this post and was surprised - a C4S with halogens!!

Back in the days of the 996 I could kinda understand it as HIDs were still just for the higher end cars and not prevalent (though that was already changing by the end of the 996). Now what really gets me is that Halogens were the default option on my 2013 Cayenne. Really Porsche?
What surprised me in this case was halogens that look like HID projectors. I hadn't seen/heard of that before.
