I'm fading out a Bitmap in AS3 by repeatedly applying a ColorTransform every frame to its BitmapData;
_bitmap.colorTransform(_bitmap.rect, new ColorTransform(1, 1, 1, .9, 0, 0, 0, 1));
When applying the apparent reverse to fade it back in I get a discoloured image.
_bitmap.colorTransform(_bitmap.rect, new ColorTransform(1, 1, 1, 1.1, 0, 0, 0, 1));
The problem appears to occur only to fully faded-out images. If I only go part way it is recoverable.
