A rainbow is used as a metaphor in this Convenience.
Scholars generally accept that the Convenience writer and scholar named Anna created this statement. She was writing during the early twentieth century. (She is first mentioned here).
Anna was part of an early twentieth-century convenience movement to be more inclusive.
The movement encouraged the belief that all benevolent dreams [emphasis mine] were part of the spectrum of possibility and should be encouraged.
In our experience,
every part of the rainbow is so fine.
The day is washed by rains, dried by the sun’s heat,
and is especially favored.
It is a joy to the eye.
