If you have ever watched an interceptor launch you will see that the entire missile is painted, ... wait for it... WHITE!
I was near (~300 meters) when an Iron Dome battery lit off unexpectedly (to me).
They are LOUD. I believe the ordinance hits supersonic pretty much at the launchpad. The sonic boom knocked me on my ass.
Or, it could have been the glass of wine I was enjoying sitting on my friends back porch. We ran for the wine cellar. Had time to bring the open bottle, of course.
