"The Man with the Blue Guitar XIII" Wallace Stevens

XIII
The pale intrusions into blue
Are corrupting pallors...ay di mi,

Blue buds of pitchy blooms. Be content--
Expansions, diffusions--content to be

The unspotted imbecile revery,
The heraldic center of the world

Of blue, blue sleek with a hundred chins,
The amorist Adjective aflame...

"Blue Winter" Robert Francis

Winter uses all the blues there are
One shade of blue for water, one for ice,
Another blue for shadows over snow.
The clear or cloudy sky uses blue twice -
Both different blues. And hills row after row
Are coloured blue according to how far.
You know the bluejay's double-blue device
Shows best when there are no green leaves to show.
And Sirius is a winterbluegreen star.

"The Mystic Blue" D.H. Lawrence

Out of the darkness, fretted sometimes in its sleeping,
Jets of sparks in fountains of blue come leaping
To sight, revealing a secret, numberless secrets keeping.

Sometimes the darkness trapped within a wheel
Runs into speed like a dream, the blue of the steel
Showing the rocking darkness now a-reel.

And out of the invisible, streams of bright blue drops
Rain from the showery heavens, and bright blue crops
Surge from the under-dark to their ladder-tops.

And all the manifold blue and joyous eyes,
The rainbow arching over in the skies,
New sparks of wonder opening in surprise.

All these pure things come foam and spray of the sea
Of Darkness abundant, which shaken mysteriously,
Breaks into dazzle of living, as dolphins that leap from the sea
Of midnight shake it to fire, so the secret of death we see.
