You can set that color to any hidden test element(default color white) on page. then retrieve the color property from that element. if its other than white, then color is valid. else it is not.

$('#testelement').css('background-color', colorstring);
var coloris = !(/\d/.test(colorstring)) && (colorstring == "white" || $('#testelement').css('background-color') != "rgb(255, 255, 255)")   ? "valid" : "invalid";
alert(colorstring +' is '+ coloris );
