The right edge of the dewbow is shown in more detail.
Notice the brighter white region inside the bow, exactly the same as a normal rainbow.
The colours aren't strong here but were more obvious from a moving car.

The water repellant nature of the leaves means the drops hold their shape well, leading to a strong heiligenschein. I've only noticed the coloured bow on mornings when there has been a heavy dew, so it probably does matter whether the drops are formed gently by dew or by the wetting action of heavy rain. |
