Blue as blue as blue is blue.

Blue, good dog.
You're our boy, Blue.

You are blue enough for the lot of us.
Your blues are blown to trumpets.

You sweeten our blue with indigo.
You are the bluest blue this side of sky.

Your ocean is deep, never too green.
You are a wolfsbane beam, benign.

Your pastels sip oil to prove blue.
Chemistry cannot react to a blue as blue as you.
