Famous quotes containing the word yellow:
“But we are spirits of another sort.
I with the morning’s love have oft made sport,
And like a forester the groves may tread
Even till the eastern gate, all fiery-red,
Opening on Neptune with fair blessèd beams,
Turns unto yellow gold his salt green streams.”
—William Shakespeare (1564–1616)
