I'm no expert, but it looks like Rose to me. Have you checked for a grill? There's information about this stamp at.... http://www.theswedishtiger.com/ID65.html Good luck.
It very hard to tell subtle colors from a scan. I would agree with Gunny on Rose being the most likely.
Here is a pink compare yours to it see how light it is. overall< there is also a Rose pink go to .theswedishtiger.com for all comparisons.
