What is a good name for my black lab ?

I am watching 2 border collie lab mixes from the pound. Right now we named the girl Daisy and the boy Duke. Originally I was just watching them til they find homes but now I am thinking of adopting the boy he is black and looks just like a black lab puppy. So I need a new name for him I was thinking Blaze, or Haze what do you guys think? Any other suggestions? P.S. He's a real chill and relaxed puppy.
