You have to extract the color channels:

for (var j = 0; j < bmpd.width; j++) {
    for (var k = 0; k < bmpd.height; k++) {
        // Read the pixel color
        var color:uint = bmpd.getPixel(j, k);

        // Read color channel values
        var alpha:uint = color >> 24 & 0xFF;
        var red:uint   = color >> 16 & 0xFF;
        var green:uint = color >> 8 & 0xFF;
        var blue:uint  = color & 0xFF;

        // Reassemble the color
        trace("color: 0x" + red.toString(16) + green.toString(16) + blue.toString(16));
        trace("alpha: 0x" + alpha.toString(16));
    }
}

To get a color on your MovieClip at a certain point or range, you should create a transparent BitmapData of required capacity (1x1 for point), fill it with 0x0 color, then create a transform matrix aligning (0,0) of BitmapData to upper left corner of your region, then draw that MC on the bitmap, then you can query its pixels. An example (a point):

private static var hitTestBD:BitmapData=new BitmapData(1,1,true,0);
private static vat hitTestMatrix:Matrix=new Matrix(); 
public static function getMCColor(mc:DisplayObject,tx:Number,ty:Number):uint {
    hitTestMatrix.identity();
    hitTestMatrix.translate(-1*tx,-1*ty); // aligning
    hitTestBD.fillRect(hitTestBD.rect,0x0);
    hitTestBD.draw(mc,hitTestMatrix);
    return hitTestBD.getPixel32(0,0);
}
