I think it has something to do with Raynaud's disease. That means that when it's cold, your veins narrow, causing the flow of blood to your hands or feet to decrease or even stop. Result: your fingers/toes turn white or even blue. Normally, this stops after a few minutes or hours and then they turn pink again. During this process, your fingers can tingle or hurt.

The best thing to do is keep yourself warm and avoid smoking, because that could also trigger it.

I'm not one hundred percent sure whether it's right, but that's what I read about it.

Why would a white gold engagement ring turn your finger brownish-orange?

The discoloration could be caused by a reaction between the natural oils in your skin and the alloys used in the white gold. This reaction can create a film on the ring surface, leading to the brownish-orange color on your finger. Regular cleaning and maintenance of the ring can help prevent this issue.
