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 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.
