Sun with a blue tinge

I was being driven on one of the freeways in California when there was a stretch of clear road and the sun was just on the way up. So took a chance that this might come out well, and managed to get this photo.
Of course, this photo is also raw from the camera, and no software editing has happened. And yet you see the blue tinge at the top (would be a pretty interesting natural phenomenon), well well, that is actually the small blue band at the top of the car's windshield through which the sun's rays are shining through.
