How do I change the background color of my search box?

I'm trying to tweak the this template

http://icompany.ithemes.com/

and I want to make the white background of the search form a different color, probably (#CECECE). What attribute do I need to add to make that change. Here's the code from the style.css. Thanks for the help.

#header #search {
display: block;
width: 200px;
float: left;
text-align: right;
margin: 5px; padding: 55px 20px 0px 0px;
}
#search form {
display: block;
margin: 0px; padding: 0px 0px 0px 0px;
background: url(images/search.gif) right 5px no-repeat;
}
#search form #submit {
width: 10px;
background: transparent;
border: none;
margin: 0px; padding: 0px;

 

You need to add to your css

#s {
color:#000 ;/*the color of text in input field */
background:#CECECE;/* the background color of input search field */
}
