    Probably nickel and/or salts of barium. Copper burns blue as a pyrotechnic colorant.

      Ah ok. I was going to say nickel but I did a quick search and somehow I read that it was copper.

      Depending on the salt you can make both blue and green. Copper sulphate flame test is a pretty common school lab practical isn’t it?
