SWF does not support transparent background color. If you want transparent background of SWF played on webpage, you can set it in HTML object parameters. We use default color selection dialog which also allows to change Alpha channel. Modifying the dialog to hide alpha would not be easy. So we use that dialog and the alpha channel is lost when saved.

In past few versions we disabled the alpha slider for colors without alpha channel allowed. I am closing this.
