         There are varying chems for any given color.

         ...and other places to get them.



>place to make colored sparks.

         Classically:
                 Sr (Strontium) for red
                 Cu (Copper) for blue
                 Ba (Barium) for green
                 Ca (Calcium) orange

         In General, chems go in as 'salts' (nitrates,
         perchlorates, chlorides ...).  Degree of color
         'saturation' and 'tint' are variable.  Mixing
         chems to get varying shades is tricky with
         incompatibility.

         Some chems are hazardous (toxic, unstable),
         and some 'attract regulatory attention' as they
         can get used for other things...

         There are web sites on pyrotechnics which discuss
         this in huge, and, sometimes, experienced detail.
         ...and sell reference books.
