You could simply set the color to a dummy element and then check if the element's value is something other than white.

colorToTest = 'lime'; // 'lightgray' does not work for IE

$('#dummy').css('backgroundColor', 'white');
$('#dummy').css('backgroundColor', colorToTest);
if ($('#dummy').css('backgroundColor') != 'rgb(255, 255, 255)' || colorToTest == 'white') {
    alert(colorToTest+' is valid');
}
