Hi It looks like ivory to me...
I think it is also, wilton has ivory icing color you could use for the fondant. I got some and thats about the color I got.
how about a tiny drop of brown?
Ifyou don't have ivory MAYBE you could use a TINY bit of brown
I would use a very tiny drop of copper it starts off ivory then goes into gold when you use more. So start off with a tiny bit.
