Try using background gradients. My example is a little crude so you'll need to play with it.
http://www.colorzilla.com/gradient-editor/
CSS:
html {background: #208FE5}
body {
background: #FFFFFF; /* Old browsers */
background: -moz-linear-gradient(top, #000000 0%, #ffffff 28%, #ffffff 71%, #208fe5 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#000000), color-stop(28%,#ffffff), color-stop(71%,#ffffff), color-stop(100%,#208fe5)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top, #000000 0%,#ffffff 28%,#ffffff 71%,#208fe5 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top, #000000 0%,#ffffff 28%,#ffffff 71%,#208fe5 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(top, #000000 0%,#ffffff 28%,#ffffff 71%,#208fe5 100%); /* IE10+ */
background: linear-gradient(top, #000000 0%,#ffffff 28%,#ffffff 71%,#208fe5 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#000000', endColorstr='#208fe5',GradientType=0 ); /* IE6-9 */
}
NOTE: It won't look the same in pre-IE10 so you might want to feed those miserable browsers a background image instead of using IE filters.
