looking for the colors of gold thread

[akmiss]

Hello,

I am searching for a new wedding band preferably a pinkish/red one. I recall a thread years ago discussing the colors of gold and would like to reference it but cannot find it in the search menu.

I am currently looking at this George Sawyer 18k red gold band and Pearlman's gave me a fair quote

it is the middle red band-

I am intrigued by this because it is has a strong rose hue.

any advice or a link to the colors of gold thread would be great! Thanks!
