Page color not the same in firefox as ie

I am using dreamweaver cs5 and when I test my page in firefox, it is the color that I chose ( a pink color), but when i test it in internet explorer, it is black (this is the background color). Does anyone know why this is happening and how to correct it?

Also, I made my page with tables and centered the table with no margins. well the page has a huge margin gap at the bottom in google browser, but it is fine in IE and firefox. any suggestions? Thanks.
