I am also Asian and went for the rose gold. On my skin it looks more like a pale yellow gold than a true rose gold (for example I have a lot of costume jewelry that Is "rose gold"). I love the way it looks. The yellow gold definitely stood out more on my skin and I didn't want that for every day, but to each their own. In terms of discoloration, I would say that it hasn't changed on me. I have compared rose gold Cartier items that are about 3-4 years apart and they look the same. I would say it's slightly more pink than the Tiffany rose gold. So subtle thought that a it's difficult to tell the difference except in direct sunlight. If you can try on the colors, show pictures! I have never worn yellow gold and always gravitated towards white gold, but the Cartier rose gold looks fab on my skin! Now I wear the LOVE bracelet, a JUC with diamonds ring and a thumb ring all in rose gold!
