I'm gonna guess that it's the dulling-out phase in the shed process. With my normal girl, her belly will get a slight pinkish tint to it, then it will dull back out to a cream, off-white color. A couple days later, her eyes will begin to cloud up, then clear up, then she sheds... I'd say to post pics if possible, but I imagine that within a week, you'll have a freshly shed snake...
