theme color wont change

it wrks for me… put background: #ADD8E6. it will wrk

look here for the blue of your dreams —> http://heavendream.de/quick/sonstiges/colors.html
your hex for light blue #ADD8E6 wuld be correct but you did sth unnice to your code. it should be like this:
body {
background: #ADD8E6;
border: 2px solid #565;
border-bottom: 1px solid #565;
border-top: 3px solid #565;
color: #FF1493;
font-family: ‘Lucida Grande’, ‘Lucida Sans Unicode’, Verdana, sans-serif;
margin: 0;
padding: 0;
}
