I'm half Japanese and grew up in Japan, so I have a decent understanding how Chinese symbols work...According to the trustworthy google translate Rose Gold is 玫瑰金. And to me this does not look like what is on the bag.
(in reality I do not trust google for anything, but there does seem to be a discrepancy here)
There is always a HUGE descrepancy in how characters look handwritten compared to a font. That definitely says "rose gold' in Mandarin.
