True Moonbows
A true moonbow is lit by the Moon itself, not directly by the Sun. In contrast, a colored rainbow (or a white fogbow) seen when the sun is rising or setting, or in twilight, is not a moonbow because it is still produced by sunlight.
Moonbows have been mentioned at least since Aristotle's Meteorology (circa 350 BC), and also in an 1847 publication.

Famous quotes containing the word true:
“For true poetry, complete poetry, consists in the harmony of contraries. Hence, it is time to say aloud—and it is here above all that exceptions prove the rule—that everything that exists in nature exists in art.”
—Victor Hugo (1802–1885)
