Thank you for the question.  Your question implies that your tree has never developed fall colors.  If this is the case, it's possible that you don't have the tree you think you do.  Some sugar maples are grafted onto different tree rootstock which isn't genetically programmed to develop fall color or maybe you have a different variety of maple. For example, silver and Norway maple trees don't change color as much in the fall.  It could be that the fall fiesta maple grafting didn't "take" and the tree you have is whatever the a maple was grafted onto.  You might want to check with the nursery where you purchased the tree to find out for sure.  

There isn't any fertilizer you can apply that will change the situation.  In fact, most shade trees don't require much additional fertilizer at all.

Here are some publications that discuss why leaves change color in the fall and the fall fiesta sugar maple in detail:
