What skilful limner e'er would choose
To paint the rainbow's varying hues,
Unless to mortal it were given
To dip his brush in dyes of heaven?
- Sir Walter Scott, Marmion
(canto VI, st. 5)
I promised Kae something with Rainbows.
Sir Walter Scott has some amazing works, if you haven't read his quotes or works before, i suggest it.
