Vary
Ever varies, she can pass from gay to severe, from fancy to science—quick as thought passes from the dance of a leaf, from the tint of a rainbow, to the theory of motion, the problem of light.
—Edward Bulwer-Lytton
The color also of this mixture varies in proportion to its degrees of heat and coldness; as a burning coal, when it is hot, shines; and when it is cold, looks black.
—Robert Burton
Vary like the rainbow’s hue.
—Lord Byron
