Can you see the rainbow colour light behind the cloud?

It was a Saturday evening, I was in my garden looking at my plants, and I noticed this light was above the horizon on the west.  The first impression that came into my mind was it looked like a mushroom.  When I looked carefully again, it was actually in rainbow colour and very bright.

 I quickly told Siew Peng, my parents and my brother to have a look, at the same time i went to take the camera.  Unfortunately, the Olympus camera battery power has ran out.  Clement (my brother) quickly took his mp4 player with build-in camera, and has taken the these pictures.

As the time passed while I took my time to get the camera, the rainbow colour and brighness has faded.  But the shape was still there.  Luckily we still have taken few pictures.

 My colleague asked me to show her these pictures, because something happened coincidently on that day.

The rainbow light was behind the cloud, there may be also a story hidden behind the rainbow light.
