Yellow gold filled vs white gold filled

[Dave Berghold]

I have noticed something that I thought I ask about here. Gold filled Keystone Howard watch cases (in 16 size) are all yellow gold filled with the exception of the Ser. 11 RR. Chronometer. Has anyone else noticed this? Once you get into the 10,12 size variety, there are plenty of each.... maybe more white gold filled.
Any thoughts?

Possibly a dress statement?
