Strangly enough, this code, returns "#00AAFF" color format:

                       
             <script language="JavaScript" type="text/JavaScript">
function showColor(obj) {
  myColor = obj;
  alert(myColor);
  alert(myColor.style.color);
}
</script>
<body>
<span id="test" style="color:#009933; font-weight:bold" onClick="showColor(this);">Click me!</span>
</body>

I mistyped the function name above. This:
for( var i=0; i < d.length; ++i)
d[i]=d2d(d[i]);

should have been:
for( var i=0; i < d.length; ++i)
d[i]=d2h(d[i]);

The previous d2h() does not allow leading zeroes. Here are the revised functions.

> Strangly enough, this code, returns "#00AAFF" color format:

It depends on the browser. Some browsers return hex format, others return the rgb() decimal format.
