'65 Fog Light Color

I currently have clear fog light seald beams in my July 1965 Dearborn built K GT.

One just blew and I will be ordering a replacement soon and actually now I am wondering about the proper use of the AMBER ones?? I really don't particularly like the look of the amber......is either one really more correct than the other??

I remember back in 1973 when I bought my first '65 K GT that the bulbs were clear and there was a GT Coupe in the neighborhood (I think a '66) that had the amber ones....I don't care for the look of the amber ones, and besides all of todays vehicles that have factory fog lights are clear so thats what I'm going to stay with.
