Double Rainbow

  
If you look to the very left of the picture, you can faintly see the ‘second’ rainbow. Jim informs me that every rainbow has a double, and the colours are reversed. So although it follows the same curve as the primary rainbow, the outer colour is purple/violet and the inner colour is red.

Autumn may be blustery and the weather may be unpredictable, but at least it gives us rainbows.
