function toHex(color) {
var body = createPopup().document.body,
range = body.createTextRange();
body.style.color = color;
var value = range.queryCommandValue("ForeColor");
value = ((value & 0x0000ff) << 16) | (value & 0x00ff00) | ((value & 0xff0000) >>> 16);
value = value.toString(16);
return "#000000".slice(0, 7 - value.length) + value;
};
var body = createPopup().document.body,
range = body.createTextRange();
body.style.color = color;
var value = range.queryCommandValue("ForeColor");
value = ((value & 0x0000ff) << 16) | (value & 0x00ff00) | ((value & 0xff0000) >>> 16);
value = value.toString(16);
return "#000000".slice(0, 7 - value.length) + value;
};
For other browsers you can use
getComputedStyle() so that is already a solved problem.
