The phrase "the grand crayon of Arizona” is, inexplicably, a Googlewhack.  Yet the great gorge in Arizona is, indeed, a crayon box of colors, as Jonathan Caws-Elwitt has proven:

The color of God is "white of god red black and everything."  From Visions of Gerard by Jack Kerouac, 1963.

It's a Googlewhack to this day: "To see how color flies through kaleidoscopic eyes, you must start the spinning gyre and consure each day in fire."  From Hollins' 1962 yearbook.

Though Wikipedia won't tell you this, "Lavender's Blue," the old English folk song, was the original "[You Say Tomato, I Say To-mah-to,] Let's Call the Whole Thing Off."  "Lavender's blue, dilly dilly, lavender's green."  Only in the folk song, they don't call the whole thing off just because they can't agree about the color of lavender.  Interestingly, the lyrics in the 1670s version began with the colors the other way around: "Lavender's green, diddle, diddle, lavender's blue," so the first rhyme used to be about "you" and not a once or future "queen."

Ireland as the threshold of the Otherworld, by Cornelius Weygandt, in The Sewanee Review, 1904.

You've heard of rose-colored glasses.  Here's the opposite.  However, the phrase "the world is already rose-colored" is a Googlwhack.  From Lustige Blätter, 1903.
