yes the gold is a bit shinier and i have blonde hair and wear a little teensy roberto coin tiny treasure necklace all the time that is gold - overall i just liked the gold better with my hair/necklace/skin tone. honestly though, they were much more similar than i expected and both beautiful. its' a subtle rose gold, not a super rosey gold
and YES, mine were in a box but the little tag was only attached to one of the earrings and the other one i had to dig around for. It was stuck down in the bottom of the Lana bag and had some random sticky stuff on it (from the sticker i assume) with blue bag lint stuck to it. I had to clean it off!
I hope you love them as much as me!
I have light hair as well, and mostly wear yellow gold, so the yellow is probably my best bet. Did your earrings arrive with the little clear stoppers? One pair I picked up in the store came with a plastic bag and four of these backs. The other two pairs didn't come with them.
