A very different sunset

I had to catch this one while driving and it wasn't my normal full of reds and oranges kind of sunset.  It was almost devoid of all color except a faint rainbow effect around the sun itself.  The first one I had the camera aimed a little too high but I loved the effect of the clouds.  So thick and ominous.

The "good pic" still showed those clouds but also the actual sun breaking through those thick clouds to create a pretty cool show.  Nature gives us so much to appreciate.
