Adding alpha to colorTransform

programming flash

I am trying to add alpha to a colorTransform, but it doesn’t seem to be compile the alpha value, which is the 0x88 (50%) part :



//specify error color and add it to the 'crosshair' mc
var safetyLimitColor:ColorTransform = crosshair.transform.colorTransform;
safetyLimitColor.color = 0x88FF0000;


//specify safe color and add it to the 'crosshair' mc
var safetyOkColor:ColorTransform = crosshair.transform.colorTransform;
safetyOkColor.color = 0x8800CBFF;

//start the mc out with safe color
crosshair.transform.colorTransform = safetyOkColor;
