16进制转rgb：

function HhtmlColorToRGB(color) {
var str="0x" + color.substring(1,color.length);
var r=str&0x0000FF; 
var g=(str&0x00FF00)>>8; 
var b=(str&0xFF0000)>>16; 
return b + "," + g + "," + r;
}

rgb转16进制：

function colorRGBtoHex(color) {
    var rgb = color.split(',');
    var r = parseInt(rgb[0].split('(')[1]);
    var g = parseInt(rgb[1]);
    var b = parseInt(rgb[2].split(')')[0]);
    var hex = "#" + ((1 << 24) + (r << 16) + (g << 8) + b).toString(16).slice(1);
    return hex;
}
