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 colored blue according to how for.
You know the bluejay's double-blur device
Shows best when there are no green leaves to show.
And Sirius is a winterbluegreen star.
(Robert Frost, 'Blue Winter' )
