Gold at the end of the rainbow

What an incredible sight this afternoon walking the dog. The sky and the colours were stunning with the rainbow lighting up the wind turbines.  

I watched in amazement as the sky got more and more orange and I've added some extras so you can see what I mean.

But it was all over in half an hour though still beautiful as the colours faded.

BTW I haven't adjusted the saturation the real colours were pretty unreal!
