​

The times that the white rainbow appears

​

Some sources indicate that the white rainbow ofter appears above Maunakea.

​

Manaʻo ʻia e kekahi kumu, ʻike pinepine ʻia ke ānuenue keʻokeʻo ma luna o Maunakea.[1] In the scientific view, the color that the observer sees is dependent on the diameter of the water drops, 1mm or more for a bright rainbow. If the diameter shrinks the red color is dimmed. In a fine mist the various colors disappear with the exception of the violet, and if the water drop diameter is 0.05 mm or less, the colors overlap and the result is a white rainbow.[2]

​
