Footer with another color

Hello, how to let the whole footer area with another color?
I saw that I can change code as below:

body {
background: none repeat scroll 0 0 # 012345;
color: # 666666;
font-size: 15px;
font-weight: 300;
line-height: 1.6;
margin: 0;
min-height: 100%;
padding: 56px 0 0;
word-wrap: break-word;
}


However, I would like the footer had its own code without interfering in other areas.

Hi,
I checked twice, and probably you have to use only another color in body.

Because footer is inside #gkFooter - and it too small box to hold whole background area.
