How can I email Martha Stewart?

I used Martha Stewart colors in my house a few years ago, and went to do touch ups. She has moved vendors, and now all the color bases are different and nothing matches. I have spent lots of money on new paints, and even more having to repaint walls that only needed tiny fixes. No warning that these colors would no longer be the same as before. Not acceptable!! I want to let her know and I want my money back!! So I need her email address.
