Slightly Off White Why Is My MM Fondant Off-white This Time?

Why is my MM Fondant off-white this time? - slightly off white

So I started to wedding cakes and I just 20 pounds today marshmallow fondant. LOTS of consoles!

Anyway ... I have fondant is a little off-white kind of ivory instead of white light that I wanted.

then ... If anyone knows why and how the marshmallow white and shiny, the next time basis, let me know. This could be the make or chocolate? Sugar? Do I just simply blown to Jet stick Domino Sugar? If you have not chosen this time to mark save moola.

Let me know
Thanks
