Change Background Color

This is very frustrating. I’m trying to simply change the default grey background color to another color but nothing is happening. I’ve read many posts in the forum but nothing is working. Below is the section I have zeroed in on, changing the color#, removing the image, even removing everything. Nothing happens. It seems that I can make any change I want, update the file, and NOTHING. I am new to WP and have the latest version, other than the Beta that may have just came out. Any suggestions appreciated, thank you.

body {
font-size: 62.5%; /* Resets 1em to 10px */
font-family: ‘Lucida Grande’, Verdana, Arial, Sans-Serif;
background: #d5d6d7 url(‘images/kubrickbgcolor.jpg’);
color: #333;
text-align: center;
}
