I've lost my mind.

I am trying to write a very simple webpage using html. I already know html, and am referring to w3schools wherever necessary. I am trying to add a background color to the page, and a different background color to a cell in the table I am using to divide up the page. My html is correct, I am sure of it. The colors are coming out varying shades of teal no matter what code I use. I am going nuts here. I would assume the trouble rests with trying to give the cell a different color background, only the page background isn't the right color either. WHAT IS GOING ON? I tried removing the color from the cell and the background color is still wrong. And yes, I tried it in Safari, too. It isn't a browser thing.

EDIT: Heath made it better.
