to me it looks more like the dip that is always present in that test... cannot rightfully say that it looks pink. The bottom half could possibly maybe look pink but really... it just looks like because she is holding it with the light to the left... that you are seeing the indentation where a bfp would be.
She should take a pic of it sitting down on a flat surface with light directly above rather than to the side.
