Apply [None] Color in TextFrame contents

Hi all,

Is it possible to apply [None] Swatch/Color to a TextFrame contents ?

I currently use this:

var vNoneColor = app.swatches.itemByName("None");

for (var iText=0; iText < vTextFrame.texts.length ; iText++)

{

        var vText = vTextFrame.texts.item(iText);

        alert(vText.contents);

        vText.fillColor = vNoneColor

}

or maybe create my own Color but it's not possible to change transparency.

Thanks.

Regards,

Pierre RAFFA.
