Colors off both sides of the spectrum from white reduce eyestrain, FYI. The best thing about fog lights and driving lights is that you have a handy switch to turn them on or off. Glare can be eliminated, but you have to modify your housing, and it's not NECESSARY to have projectors to use HIDs. Many car manufacturers use non-projector HIDs. Projectors typically do focus the light more evenly on the road though. Anyway, do what you want to do for the fog lights. You can go ahead and install whatever you want, as it's your own customization and don't let anyone else shove their opinion of how they would do their car on you.
If you install them and like them, go 200 yards away from the car at night and see what glare they give off. If they're distracting, I would recommend only using them in the conditions for which they were originally designed. Projectors can give off incredible amounts of glare, as they are designed to allow a small amount of light to reflect up onto street signs. This can be distracting, but not all conversions result in distracting glare. Good luck. I am personally a full supporter of getting the best lighting you can get for your vehicle. I don't want to harm others with them, so I say just be smart about it. Fog lights may not be that distracting in your vehicle. Good luck.
