Use bitmapData & Matrix class for any type of image editing related work.
These are lower level api so you have to do struggle.

Not quite sure if the color is same across entire image. If yes, then this is
what you can do:

Let's say you have an image which if fully red in color(which may be an
outline or content) and on some action if you want to turn that to green,
you can use this method:

changeImageColor(yourBitmapImage, 0xff0000(your image's color : red),
0x00ff00(green color));
           
            private var colorTransform:ColorTransform;
            private function changeImageColor(image:BitmapImage,
originalColor:uint, newColorToBeApplied:uint):void
            {
                if(!colorTransform)
                {
                    colorTransform = new ColorTransform();
                }
                colorTransform.redOffset = ((newColorToBeApplied & (0xFF <<
16)) >> 16) - ((originalColor & (0xFF << 16)) >> 16);
                colorTransform.greenOffset = ((newColorToBeApplied & (0xFF
<< 8)) >> 8) - ((originalColor & (0xFF << 8)) >> 8);
                colorTransform.blueOffset = (newColorToBeApplied & 0xFF) -
(originalColor & 0xFF);
                colorTransform.alphaMultiplier = 1;
               
                displayObject.transform.colorTransform = colorTransform;
            }
