[CS5 - JS] Convert InDesign colors to Hex

Question

Hi,
I assembled the following functions in order to convert InDesign colors to theyr hex value.
I tested it with some colors but RGB conversion is not working as expected.
function colorToHex(color, tint){
    switch(color.space){
        case ColorSpace.CMYK:
        return cmykToHex((color.colorValue[0] * tint) / 100, (color.colorValue[1] * tint) / 100, (color.colorValue[2] * tint) / 100, (color.colorValue[3] * tint) / 100);
            break;
        case ColorSpace.RGB:
        return cp_RgbToHex((color.colorValue[0] * tint) / 100, (color.colorValue[1] * tint) / 100, (color.colorValue[2] * tint) / 100);
            break;
        default:
        return "";
            break;
function cmykToHex(c, m, y, k){
    c = c/100;
    m = m/100;
    y = y/100;
    k = k/100;
    var R = (1 - (c * (1 - k) + k)) * 255;
    var G = (1 - (m * (1 - k) + k)) * 255;
    var B = (1 - (y * (1 - k) + k)) * 255;
    return rgbToHex(R, G, B);
function rgbToHex(R, G, B){
    return "#" + nToHex(R) + nToHex(G) + nToHex(B);
function nToHex(N){
    if (N == 0 || isNaN(N)){
        return "00";
    N = Math.max(0,N);
    N = Math.min(N,255);
    N = Math.round(N);
    return "0123456789ABCDEF".charAt((N-N%16)/16) + "0123456789ABCDEF".charAt(N%16);
Do you see something wrong?
Thanks!

What I meant to say was "InDesign uses an advanced internal system". There is simply no way you could do the same with Javascript.
But to use InDesign's color conversion, all you have to do is
If you want to get the 'good' RGB value, let InDesign convert the color from CMYK to RGB for you by changing the ColorSpace property of the swatch.
