What would cause the blooms of a Calla Lily to turn from white to green? Is this normal?

No its not normal. However, some Calla Lilies are more green than others and thats just the type they are. If they've always been white and now all of a sudden have changed color, it could be a soil issue.

Have you changed, added, or taken anything out of the soil recently? Maybe its a reaction to some fertilizer or pesticide. You may want to research the soil requirements for it and then get a soil testing kit (you can find a cheap one out there under $10) to see how your soil compares to what should be. Also, it could be related to weather.
